Hello,
I am using "OPA211-HT" (since it is available in KGD form). With unity gain for input voltage from 0 to 3.3V, I get linear output. But when I set gain to 4.16, I see non liner behavior for input voltage below 1.25V. If it is due to common mode voltage limitation, why do we have it only with higher gain?.
Thanks,
