Forum Post: RE: ADS8638: HVDD Supply doubt
Hi Aditya, You can power the ADS8638 from +/- 5V. You can also take a look at the ADS8668, 500kSPS with only a single 5V supply needed. We also have the ADS8686S, that can reach 1MSPS and has 16...

Hi Jeeveth, TXB is not designed for open drain drivers due to its weak push-pull drivers. For open drain level shifting, the TXS-Type translators should be used instead (note that this device includes...

Hi JH, Can you expand a little of what sort of features you are looking for? What is it about the ADS7866 that you like? Internal reference? Low voltage supply?
View ArticleForum Post: RE: ADS1262: Timing questions about ADS1262 SPI interface
Hi Tiziano Pigliacelli, Are you starting the SCLK period before you bring CS low? Most SPI peripherals I am aware of bring CS low and then start sending SCLKs. In this case, an SCLK period of 1us...

Hi dan log, The ADS1256 is a multiplexed delta-sigma ADC, which has conversion latency due to the digital filter. In other words, the filter needs to reset every time you change the channel, which...

Hi Haiyang, You would need to use Mode 0 (see Figure 1). The AMC1210 reads the bit stream on the rising edge of the modulator clock while the AMC1306 transitions its output data on the rising edge of...

Hi Hiroyuki-san, Both your schematic and I2C sequence looks correct to me. You are sending the correct data to update the DAC output, and it looks like the DAC is acknowledging the I2C commands. Do...

No Simon, the reference would not cause this behaviour. It sounds like you are in standby mode. Can you try setting /CS high immediately after the 32-bit transfer and then toggle it low just before...

Hi Amara, You say enable is left as default (not driven by the Arduino), but there are two possible default states on the EVM. The same is true for all of the digital signals. Can you make sure JMP1 -...

Hello Katlynne Jones, Thank you for your quick response. I'm currently using the default settings for JMP1–JMP4 as I'm not fully aware of the required configuration. The Enable pin is connected to GND...

Hi Ziming, Can you reattach the logic capture? It is a little low resolution, and I can't quite make out the numbers. Regards, Joel

Hi Andrea, To summarize, I think you are saying the following two things. 1. Output data is not PRBS 2. If the output data was prbs_data[15:2], then each bit should have been a shifted version of the...

Hello David, Welcome to the TI E2E community. I do not see anything wrong with your schematics. I assume when you change the reference voltage, the voltage at the ADC inputs does not change, in which...

Hi Dries, Is 188.7 the mean code? how many data did you collected from the ADC? External common capacitors should not increase the offset error, the EVM board has differential and common mode...
