2.3.2 The PGA Initialization Delay Does Not Work Outside Low Latency Mode

The initialization delay for the PGA does not start when the LOWLAT bit is ‘0’. This may cause a corrupt conversion when the PGA is the module with the slowest initialization time. When using the internal references, this is not an issue because of a slower initialization delay.

Work Around

Set the ADC in low latency mode by setting the Low Latency (LOWLAT) bit in the Control A (CTRLA) register to ‘1’.
