The settling time specifies the time until an ADC result is stable. This includes the minimum required sampling time of the ADC. The
settling time of the amplifier itself might be faster.

This includes the two OA configuration "inverting amplifier with input buffer". Both OAs need to be set to the same power mode, OAPMx.

The settling time specifies the time until an ADC result is stable. This includes the minimum required sampling time of the ADC. The
settling time of the amplifier itself might be faster.
