RE: ADS8910B: CONVST and ~CS connection and RST state
Hello Wen, Holding CONVST low when RST transitions from low-to-high is not a hard requirement, just a recommendation. In the case of a single control line for both /CS and CONVST, to exit the RESET state, the host controller can pull the /RST high...

TI Thinks Resolved
Part Number:
ADS8910B
Hello Team,
ADS8910B
gain drift typical value is +/-2.5ppm/C. May I know if we should use the standard deviation (sigma) to estimate gain drift maximum spec? For instance, +/-5 sigma (1 out of ~1.7M) max gain drift spec indicates...
