Typical values assume VDDA = 3.0 V, Temp = 25C, fADCK = 6 MHz unless otherwise stated. Typical values are for reference only and are not tested in production. 2. ADC must be configured to use the internal voltage reference (VREF_OUT) 3. PGA reference is internally connected to the VREF_OUT pin. If the user wishes to drive VREF_OUT with a voltage other than the output of the VREF module, the VREF module must be disabled. 4. For single ended configurations the input impedance of the driven input is RPGAD/2 5. The analog source resistance (RAS), external to MCU, should be kept as minimum as possible. Increased RAS causes drop in PGA gain without affecting other performances. This is not dependent on ADC clock frequency. 6. The minimum sampling time is dependent on input signal frequency and ADC mode of operation. A minimum of 1.25s time should be allowed for Fin=4 kHz at 16-bit differential mode. Recommended ADC setting is: ADLSMP=1, ADLSTS=2 at 8 MHz ADC clock. 7. ADC clock = 18 MHz, ADLSMP = 1, ADLST = 00, ADHSC = 1 8.

Typical values assume VDDA =3.0V, Temp=25C, fADCK=6MHz unless otherwise stated. 2. This current is a PGA module adder, in addition to ADC conversion currents. 3. Between IN+ and IN-. The PGA draws a DC current from the input terminals. The magnitude of the DC current is a strong function of input common mode voltage (VCM) and the PGA gain. 4. Gain = 2PGAG 5. After changing the PGA gain setting, a minimum of 2 ADC+PGA conversions should be ignored. 6. Limit the input signal swing so that the PGA does not saturate during operation.
