(1) 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.

All power modes 2.2 V, 3 V 7 12 µs
(1) This includes the 2 OA configuration "inverting amplifier with input buffer". Both OA needs to be set to the same power mode OAPMx.
(2) 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.
