42.6.9 Input Gain and Offset
The ADC has a built in Programmable Gain Amplifier (PGA) and Programmable Offset.
The Programmable Gain Amplifier can be set to gains of 1/2, 1, 2 and 4. The Programmable Gain Amplifier can be
The Programmable Gain Amplifier can be set to gains of 1/2, 1, 2 and 4. The Programmable Gain Amplifier can be
used either for single ended applications or for fully differential applications.
If ANACH is set in ADC_MR the ADC can apply different gain and offset on each channel. Otherwise the
If ANACH is set in ADC_MR the ADC can apply different gain and offset on each channel. Otherwise the
parameters of CH0 are applied to all channels.
