Forum Post: TSW14J57EVM: Error 1149 occurred in [Auto Re-Arm Trigger Option] with ADC12DJ3200EVM.
Part Number: TSW14J57EVM Other Parts Discussed in Thread: ADC12DJ3200 Hi, We encountered the problem as the title discribed. More specifically, we use the dual channel mode, i.e., JMODE3 as the table 19 in ADC12DJ3200's pdf. However, since we didn't find the [trigger ini file] in HSDC v6.0 software, we created a new file based on the the ADC12DJxx00_JMODE3.ini , i.e., add a line "Menu Enable="Trigger Option" in it. All these works well for software trigger enable option & external trigger option. We can capture the data successfully. It's should be noticed that we found the Interface name should be "TSW14J57RevE_16L_XCVR_ADCDDRDACBRAM", other interface didn't work. BUT, the error occurred when we selected the Auto Re-Arm option and clicked show trigger status. We tried reintall the software & change WIN10 into English setting as advice in the similar post, but these didn't work! We really need your HELP! THE SOONER THE BETTER! Best Wishes, Lei

Forum Post: RE: AFE58JD32: ADC data acquisition problem
Hi Sachin! Thanks for you reply! I'm collecting the data at my own system and following the initialization sequence.If I don't do this, I won't be able to collect the correct ramp data, right? The cause of problem 2 was found, because the quality of the waveform generator cable was too poor, which introduced a large amount of noise.Now there are still questions (1) No reason can be found.

Forum Post: RE: ADS131E08: ADS131E08 stop in continuous mode after few minutes of running
Hello Bryan sorry for disturbing again, I have strictly followed the datasheet specifications as well as the default modes of the ADC and its operation, and I conducted a test without performing a hardware reset, with the Start pin state maintained high, ensuring that the Ready pin state is triggered by a falling edge (falling edge interruption). Additionally, I kept the Power-Down signal at 1 and the clk is set to High, without sending any configuration data or commands to configure the ADC, all while keeping the CS pin at a low level, based on this flowchart from the ADS131E08 datasheet. 1/ Can you confirm if, by keeping CS at a low level and keeping Start and Power-Down high, without sending configuration commands, the ADC automatically enters continuous mode and sends data on the SPI bus or not? 2/ Is the CS signal linked to the Ready signal? 3/ If not, by not configuring CS and keeping Start and Power-Down at high levels, can I still observe a change in the Ready signal? 4/ Finally, there is a condition specified in the datasheet (page 28) called "signal is halted." Could you confirm if there are any other conditions that may cause the same behavior as "signal is halted"? 5/ Could you please explain the right use and the mean of the DUT(annonced in the diagram attached below) and CLKSEL Pin Best Regards Azer

Forum Post: RE: ADS7830: Internal Voltage Reference Drop after I2C detect command
Hi Tom, In fact, 0x48 and 0X49 are the I2C address of the two ADS7830. Which is corresponding to 0x90 (7bit, 0x48), the other is corresponding to 0x92 (7bit, 0x49) And here I can provide the address map of customer's application. Why just ACK the address of ADS7830 will result in the drop of the internal reference voltage? Could you please help provide the related explanation? Thanks for your time and effort. Best, Matt.

This is how National did their datasheets. The 2.5MHz clock was used for taking all production data (see the note at the top of the page).

Hi Azer khaled, Here are the answers to your questions: [quote userid="600688" url="~/support/data-converters-group/data-converters/f/data-converters-forum/1341140/ads131e08-ads131e08-stop-in-continuous-mode-after-few-minutes-of-running/5168227#5168227"]Can you confirm if, by keeping CS at a low level and keeping Start and Power-Down high, without sending configuration commands, the ADC automatically enters continuous mode and sends data on the SPI bus or not?[/quote] The device does not send data unless you provide SCLKs. So if you are not sending SCLKs then no this will not occur. The DRDY signal should pulse at the default data rate, which is shown in the flow chart [quote userid="600688" url="~/support/data-converters-group/data-converters/f/data-converters-forum/1341140/ads131e08-ads131e08-stop-in-continuous-mode-after-few-minutes-of-running/5168227#5168227"] Is the CS signal linked to the Ready signal?[/quote] By Ready signal, do you mean DRDY? If that is what you mean, then no, CS and DRDY are not linked [quote userid="600688" url="~/support/data-converters-group/data-converters/f/data-converters-forum/1341140/ads131e08-ads131e08-stop-in-continuous-mode-after-few-minutes-of-running/5168227#5168227"] If not, by not configuring CS and keeping Start and Power-Down at high levels, can I still observe a change in the Ready signal?[/quote] Yes. This is explained clearly in the flow chart, see the second set of comments on the right [quote userid="600688" url="~/support/data-converters-group/data-converters/f/data-converters-forum/1341140/ads131e08-ads131e08-stop-in-continuous-mode-after-few-minutes-of-running/5168227#5168227"]Finally, there is a condition specified in the datasheet (page 28) called "signal is halted." Could you confirm if there are any other conditions that may cause the same behavior as "signal is halted"?[/quote] Yes, if the device is in powerdown mode. Or if you turn off an external clock, or disable the power of course [quote userid="600688" url="~/support/data-converters-group/data-converters/f/data-converters-forum/1341140/ads131e08-ads131e08-stop-in-continuous-mode-after-few-minutes-of-running/5168227#5168227"] Could you please explain the right use and the mean of the DUT(annonced in the diagram attached below) and CLKSEL Pin [/quote] DUT = device under test. This is the ADS131E08 in the flow chart CLKSEL pin = clock select pin. This allows you to select between the internal or external clock. If you want to use an external clock, you will need to provide this signal to the ADC. -Bryan

Forum Post: RE: ADC12DJ5200RF: adc12dj5200rf abnormal status
Hello Xiaxin, Apologies for the delay, the likely reason you are not capturing sysref correctly as seen in the status of ADC REG 0x208 is that your sysref is not meeting the setup and hold time of the ADC. Can you please confirm if you are using continuous sysref AC coupled, or pulsed sysref DC coupled? Additionally, the ADC has some internal features to aid in the capture of sysref at very high sampling rates. Please look into section 7.3.6.3 of the ADC datasheet, there are two methods of sysref calibration, sysref windowing and automatic sysref calibration, for your purposes I think either should work. Best, Eric

Forum Post: ADS1278: Reference voltage
Part Number: ADS1278 Hi team, I am working in the project of ADC. In this project using ADS1278.l have some queries about the reference voltage section. Configering the Single ended reference voltage VRefP 2.5V and VRefN GND .lower voltage 0,and Higher voltage level 2.5.I am not give the differential signal.But output of the Digital code maximum voltage level is 1.25V .I will give the 2V but reaches the 1.25V the voltage is maimum digital value is saturated(7FFFFF). How will be configer the digital value to change the singlended . In ADS1278 AVDD is 5 volt But the maximum Reference voltage level( VRef ) is 2.5 volt how to caluclate the remaining 2.5 volt. And in the data sheet Differential signal calculate is given.But not give the single Ended signal calculation Give me a reference and clarifying the dought. Thanks & Regards, Aravind.SR

Forum Post: RE: ADC12DJ5200RF: adc12dj5200rf abnormal status
Thank you very much for your answer. I have found the problem now that the ROUTB of LMX2594 did not output the SYSREF signal of 31.25MHz.I found that when I set RoutB to DCLK as RoutA, it has output, but when I set Routb to sysref, there is no output. Can you help me find the reason why LMX2594 does not output RoutB according to the LMX2594 configuration provided above? In addition, do you mentioned "There are two methods of sysref calibration, sysref windowing and automatic sysref calibration" means that these two ways, just choose one? In other words, if I chose Sysref Windowing Mode (read back registers 0x2c, 0x2d, and 0x2e to configure 0x29), then I don't need to use Automatic Sysref Calibration mode? Regards, Xiaxin

Forum Post: RE: UCD3138: UCD3138EVMCC64EVM-030
Hello Tasmiya, I do not understand what your goal is and the purpose of the DC power supply is for. Power to the UCD control card is either supplied by the PMBus or the I/O connector on pin 40. Use a jumper to toggle between the two voltage sources (short J2 for PMBus source and J6 for I/O source). You can configure a GPIO by toggling the pin's GPIO bit. Please see section 9.9 on page 364 of the UCD 31xx TRM: https://www.ti.com/lit/ug/sniu028d/sniu028d.pdf If this post or the other E2E post answered your question, then please click the green "This Resolved My Issue" button.

Hello Aravind, The ADS1278 only outputs two's complement binary, as shown in Table 5. If you would like to get the entire code range, connect the AINN pin to Vref=2.5V. With AINP=0V, you will get the maximum negative code of 800000h and with AINP=5V, you will get the maximum positive code of 7FFFFFh. Converting the result to a signed 32b integer, you can then add 2^23 which will result in a value from 0 (AINP=0V) to 2^24-1 (AINP=5V) Regards, Keith Nicholas Precision ADC Applications

Hello, If you are using the ADC GUI to program the evm the RF out B of the lmx2594 is by default powered down, to turn it on you can go to the LMX2594 tab and uncheck the power down checkbox. Yes there are two different methods and you just have to choose one. Best, Eric

Forum Post: ADS1605: ADS1605: Fast 32-bit (or 34-bit) parallel gpio adc input to 2434 R5 DMA?
Part Number: ADS1605 Cross-post to this ADC forum from ARM microcontroller forum Details in here: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1355892/am2434-fast-32-bit-or-34-bit-parallel-gpio-adc-input-to-2434-r5-dma Summary: Looking for (a lot of) guidance interfacing two ADS1605 ADCs (16-bit parallel data plus overrange bit, x2 ) to a 2434 R5 processor. It's more questions about pin assignment and DMA/Interrupt resource configuration on the processor than ADC usage itself, but I suspect some of the experts in this forum might have experience with that processor as well. Thanks for any input you can provide!
