also, if you simply change the gain/Full Scale setting, the ADC data becomes noisy. one needs to initiate a (re)calibration (i was not running the background cal to save power and avoid the glitch...

Hi Yuto Maeno, This delay allows external input circuitry to settle because the chopping switches interface directly with the analog inputs, so it really depends on your external circuity. You can use...

Hi Thorsten, Thank you for all the information. I see what you are doing now. Keep in mind, as the analog input frequency changes from DC, the calibration may not hold up as well, due to BW mismatch...

Hi Mo, Have you sent the SDATAC command first before reading from registers? One other "sign of life" check you can do is to probe the DRDYn pin. After supplies ramp and clock is applied, the DRDYn...
