Hi all,
Recently, I designed a simple SDR that uses some low-noise audio op-amps to amplify the weak down-converted signals and sample the IQ paths by a single ADS131M02…
Hi Bryan,
I fixed my issue, the problem was not considering the 24 bit Word length. Now that I am padding the 2 command and 2 register data bytes with a zero byte to complete a 24 bit word the register is correctly written. I was sending the command and…
To be sure, all we do is init the SPI ports, then read data. SPI is used for other circuits on the board with no issues.
We do not init any registers on the ADS131.
Init SPI, then immediately hit Sync and wait for DRDY, then read data.
If we need to configure…

Hi Team
My customer is observing a group delay of approximately 2.5 conversion periods when using this ADC. I wanted to confirm that this behavior is expected. For a delta-sigma ADC with a sinc3 filter, the expected…
Part Number: ADS131M02 Tool/software: Hi,
We have a product using a single channel of the ADS131M02 to measure a load cell signal in continuous conversion mode with a gain of 128. We've had no issues with previous batches but have found many devices…
Part Number: ADS131M02-Q1 Tool/software: "I am having trouble with the calculation that states the conversion time is 0.754 ms according to Equation 9 in Data Sheet 9.2.2.1. I would like to understand the contents of the formula so that it results in…
Part Number: ADS131M02 Other Parts Discussed in Thread: ADS131M03 Tool/software: Hi TI-Team, Could you please help with the NC Pins on the ADS131M02. The datasheet does mention what to do with unsed Pins:
9.1.1 Unused Inputs and Outputs Leave any unused…
Part Number: ADS131M02 Tool/software: hi team,
my customer is using ADS131M02 and they found that when changing the OSR configuration, the frequency of NDRY stays the same value. Do u have any advise? thanks!
Part Number: ADS131M02 Tool/software: Hello, May I ask if ADS131M02, powered by a single power supply, can have negative values for AINxN and AINxP inputs? Used for current detection, it is positive when discharging and negative when charging in the opposite…
