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.

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.
