Part Number: ADS8688 Tool/software: Hi Team, My customer tested the ADS8688 and found the TSU_CSCK is more than 30ns as below pic. In datasheet, the minimum value of TSU_CSCK is 30ns, which you can find it in the second pic. why is it? BR, Moon

Part Number: ADS1220 Tool/software: Hello, We are having problems with our ads1220 Two-wire RTD connection. We only get the full-scale output from ads1220 with PT100 connected. We can send the configurations to our adc and read them via SPI, so we can be sure that the problem is not in SPI. We are using these configurations: CFG0_PGA_BYPASS_OFF = 0x0 CFG0_GAIN_2 = (0x1 << 1) CFG0_MUX_P1N0 = (0x6 << 4) CFG1_BCS_OFF = 0x0 CFG1_TS_OFF = (0x0 << 1) CFG1_CM_SINGLE_SHOT = (0x0 << 2) CFG1_MODE_NORMAL = (0x0 << 3) CFG1_DR_STAGE4 = (0x3 << 5) CFG2_IDAC_250UA = 0x4 CFG2_PSW_ALWAYS_OPEN = (0x0 << 3) CFG2_FIR_BOTH = (0x1 << 4) CFG2_VREF_EXT_REFP0_REFN0 = (0x1 << 6) CFG3_DRDY_DEDICATED = (0x0 << 1) CFG3_I1MUX_AIN3 = (0x4 << 5) CFG3_I2MUX_DISABLE = (0x0 << 2) cfg0 = ADS1220.CFG0_PGA_BYPASS_OFF | ADS1220.CFG0_GAIN_2 | ADS1220.CFG0_MUX_P1N0 cfg1 = ADS1220.CFG1_BCS_OFF | ADS1220.CFG1_TS_OFF | ADS1220.CFG1_CM_SINGLE_SHOT | ADS1220.CFG1_MODE_NORMAL | ADS1220.CFG1_DR_STAGE4 cfg2 = ADS1220.CFG2_IDAC_250UA | ADS1220.CFG2_PSW_ALWAYS_OPEN | ADS1220.CFG2_FIR_BOTH | ADS1220.CFG2_VREF_EXT_REFP0_REFN0 cfg3 = ADS1220.CFG3_DRDY_DEDICATED | ADS1220.CFG3_I1MUX_AIN3 | ADS1220.CFG3_I2MUX_DISABLE Here is our connections.

Part Number: ADC32RF55 Tool/software: The Nyquist Zone settings in Table 8-5 "Register Programming Sequence for Device Configuration" on page P114 of the datasheet are divided into three cases based on the sampling rate, with the options starting from 640 MSPS. On the other hand, in section 6.6 "Electrical Characteristics - DC Specifications," the minimum value for the input clock frequency is 500 MSPS. Should the settings for the 500~640 MSPS range be "640-2250"?

Hi Vitalii, Please see page 25 of the datasheet below https://www.ti.com/lit/ds/symlink/adc3643.pdf?ts=1727693502754&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FADC3643#page=25 Regards, Geoff

Hi Shunya, Yes, use this section for between 500MSPS-2250MSPS. Thanks, Chase

Yes, the peak voltage for AINxN/P is 2.45V and .05V that is within the rails still.

Part Number: ADS131M08 Tool/software: Hello, According to data sheet , if we send 0x11 , we should get 0xFF28 , the reality is that we get 0x11 as from the screenshot , can you please explain:

Hi Dale, I understand the importance of clock synchronization. I have one more question. I plan to use the internal regulator for the REF voltage, but is it okay to leave the REFIN terminal OPEN? I don't plan to use the current detection function, but is it necessary to connect a capacitor or something? Thanks, Conor

Hi Moon, The ADS8688 does not influence when the SCLK starts up, that is under the control of the host processor. The datasheet highlight above is telling you that there needs to be a minimum of 30nS, which you have done with plenty of margin.

Part Number: TLV5632 Other Parts Discussed in Thread: TLV5630 , TLV5631 Tool/software: Hi, I am trying to figure out how the output voltage is calculated. - The TLV5632 is a 8 bit DAC - from the datasheet page 10 it is stated that " The output voltage (full scale determined by reference) for each channel is given by: 2*REF * { (CODE/0x1000)} [V] where: - REF is the reference voltage (2.048V from datasheet) - CODE is 0x000 to 0xFF0 for the TLV5632. In page 12 it is stated that: "The TLV5630 decodes all 12 data bits. The TLV5631 decodes D11 to D2 (D1 and D0 are ignored). T he TLV5632 decodes D11 to D4 (D3 to D0 are ignored) . I tried to calculate the range but can't figure out how the CODE is considered: - If I reference to the fact that it is 8 bit DAC then the CODE should be 000 to 0x0FF...but then I get output voltage of 0V to 0.255V - assuming 12bit register (DATA format page 11) I get potential numbers from 0 to 4096....and taking the range of 0x00 to 0xFF0 (as written above) I get 0 to 4080? so....voltages of 0V to 4.08V? so where does the (D3 to D0 are ignored) takes action? what is the correct output range? 0V to ...?

Yes I did seen this diagram, but on the page 12 the tcd is described as dclk edge to output data delay and this value is negative, I assume that data would lead the clk in this case, but maybe I interpreted it wrong?

Part Number: ADS1299 Tool/software: Dear Engineer, I am using the ADS1299FE-PDK connected via SPI to the STM32F4052 development board. The MCU SPI settings are CPOL = LOW and CPHA = 2nd Edge. However, the data I read from the logic analyzer is as follows. According to the documentation I referred to, the result should display a square wave value, but the output does not meet my expectations. Could you please advise on which settings might be incorrect? Below are the detailed test data. Additionally, I noticed that in the printed data, the start values for channels CH1 to CH4 are consistently 05, 15, 27, and 23, respectively. This is quite interesting, but I am not sure why this pattern occurs. output data: 24583-27205 SPI: MISO transfers: C0 00 00 05 79 93 15 DC 4F 26 F3 73 23 5E 3A 56569-59189 SPI: MISO transfers: C0 00

Part Number: ADS127L11 Other Parts Discussed in Thread: TPS7A20 Tool/software: Some weeks ago I had a discussion for a new application I am designing where I want to use a 24 bit ADC. Therefore I want to use the ADC127L11 for my application. I have a question wrt the power supply for this ADC,.I have to interface via SPI with a TI C2000 DSP that operates at +3V3. So for me it would be easier to use +3V3 for the ADC digital part . Therefore I can use a DC/DC converter to generate +3V3 for the digital part. For the analog section I need +5V for my current loop to voltage converter as you already sent earlier . So therefore I want to use an accurate (ultra low noise) +5V and +4.096V for the analog section. So I am thinking of generating +6V out of +24V with a DC/DC converter (I do not need much current) and using a very low noise +5V regulator for the analog part (like TPS7A20) and a +3V3 LDO for the digital part. However in fact I would prefer to generate +3V3 with a converter directly out of +24V and using an LDO for generating +5V directly out of +24V with an ultra low noise regulator. But those regulators have higher noise figures compared with the TPS7A20 (Vin max +6V) that has very low noise figures. Is it possible to use +3V3 digital supply for this ADC ( so I do not need level translation between processor and ADC) and a low noise +5V for the analog part? And waht do you think about the supplies?

Hi Gabriel! I'm so sorry for the delay in getting back to you! Your right in that the delay on SDO will make it hard to capture the data on the rising SCLK (assuming SPI mode 0). Here is a screen capture that I was able to grab in the lab: The SCLK here is ~66MHz and you can see that the controller would have a hard time capturing the data on the rising clock edge (look close at the LSB). Using one of the Source-Synchronous protocols is the best way to run the ADS8681 at full speed.

Part Number: ADS8699 Tool/software: Hi, For our application we want to sample signals from 0Hz to 10kHz with a sample-rate of 25600Hz. As anti-alias filter we want to use a 4th order butterworth filter at 10kHz. We found the ADS8699, which would fit very well for our application. Since it has already an integrated LPF 2nd order, it could minimize our design effort. Our idea is to use an additional active 2nd order LPF in front of the ADS8699, so the combination of internal and external filter should result in our required filter characteristics. To calculate the coefficients of the external filter, we need the coefficients of the internal filter. I found a digram of the filter transfer function in the datasheet in chapter 7.3.5 Second-Order, Low-Pass Filter (LPF). www.ti.com/.../ads8699.pdf But it is very hard to get the filter coefficients out of this diagram. Can you give us more details (especiallly the filter coefficients) about the ADC's internal LPF?

Thanks for checking my assumption! Saidly I'm not sure how I should implement a source-synchronous SPI communication. Can you explain it more in deepth? As far as my understanding goes, the "write" (MOSI Line) is always source-synchronous, but the "read" (MISO Line) isn't, due to the data beeing pushed out by the ADS8681.

Hello Hayasaka-san, The minimum external reference input is 2V. The ADS7960-Q1 will not support a 300mV reference voltage. Regards, Joel

Hi Tom, Really thanks for your reply. I have another question: you could see the conversion time in the datasheet as below: And in the timing diagram, you can see the conversion time= TSU_CSCK+14*CLK cycles. When the TSU_CSCK>30ns, the conversion time will bigger than 850ns. So the question is why the 850ns in the 1st pic highlighted is the "MAX" value? BR, Moon

Hello Manu, Is the customer using the ADC12DJ3200 EVM or a custom board. It is important to note that LANE0 of the ADC will not necessarily route to LANE0 of the FPGA, so they must account for an lane mapping swaps in their FW to get correct data out. Can you confirm how your customer is setting the ADC into test mode? And confirm that they are using the "Transport Layer Test Mode" Additionally can you confirm if they are using TI JESD IP or Xilinx JESD IP? It is important to note that with Xilinx JESD IP you will have to unpack the data yourself, this to me seems like it could be the issue as they are close to matching the pattern but a little bit off. Best, Eric

Part Number: ADS7038 Tool/software: This is an addendum to the thread https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1400970/ads7038-erroneous-adc-values-being-returned Whilst I was on holiday another engineer took my code and showed that we had no further issues once we had changed our ADC configuration to use 50:50 duty cycle on the clock (we originally had 40:60) – although I doubt this was the real cause of our issues Delay between transfers set to 600ns (end of one 24-byte message to the start of the next [end-to-start]). Your datasheet says we only need 600ns delay between start of one 24-byte message and the start of another [start-to-start] but our SPI register settings uses [end-to-start] so we are keeping it simple. Using this end-to-start approach just wastes a bit of time but that doesn’t matter in our case and it easily shows we meet the 600ns minimum time. Whilst all of the timings are mentioned in the datasheet I will say that I found the datasheet quite confusing to read and could certainly do with a tidy up. This means that the thread can be marked as SOLVED Darren
