1. Typical values assume VDDA =3.0V, Temp=25°C, fADCK=6MHz unless otherwise stated.
2. Between IN+ and IN-. The PGA draws a DC current from the input terminals. The magnitude of the DC current is a strong
function if input common mode voltage (VCM) and the PGA gain.
3. This is the input leakage current of the module in addition to the PAD leakage current.
4. Gain = 2PGAG
5. When the PGA gain is changed, it takes some time to settle the output for the ADC to work properly. During a gain
switching, a few ADC outputs should be discarded (minimum two data samples, may be more depending on ADC
sampling rate and time of the switching).
6. Limit the input signal swing so that the PGA does not saturate during operation. Input signal swing is dependent on the
PGA reference voltage and gain setting.

1. The DAC reference can be selected to be VDDA or the voltage output of the VREF module (VREFO)
2. A small load capacitance (47 pF) can improve the bandwidth performance of the DAC
