Hi Saad, If the gain you set in ADS131M08 is higher than 4, you will have to keep the input voltage less than AVDD-1.8V=3.3V-1.8V=1.5V. If your gain is less or equal to 4, the input voltage to AIN pin...

Thank you, Bryan, I do see similar behavior, but my question is more geared towards the sequence that I am proposing. In short will adding sync after the start and waiting for a subsequent conversion...
View ArticleForum Post: RE: [FAQ] AFE881H1: Which TI devices support the HART protocol?
TI has many DAC devices that are compatible with the HART Protocol. Some devices provide a range of analog outputs. These devices can output a voltage or current with the HART frequency-shift-keyed...

Hello Wu, I apologize for the delay in response. Are you testing with the photodiode connected or disconnected from the board? If you remove the photodiode and run the diagnostic mode, do you get an...

Hi Dale, As said before , the gain is 128. The bridge excitation is the same as AVDD of the ads131 which means that we must have AVDD to be 3.6V at least to allow for (3.6-1.8=1.8V) of the bridge mid...

Hi, So, if your A0 and A1 pins are grounded, I believe the first 7 bits of the address are defined as 1001000 (0x48). But, if you tie to the 3.3V supply, the address will be 1001011, which would be...

Hi George Sarkees, The SYNC command just restarts the conversion, basically the same as taking START high. I don't know why this would change the behavior of your system. Also, the datasheet...
