1. Typical values assume VDDA = 3.0 V, Temp = 25°C, 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 (VREFOUT)

3. PGA reference connected to the VREFOUT pin. If the user wishes to drive VREFOUT with a voltage other than the output

of the VREF module, the VREF module must be disabled.

4. For single ended configurations the input impedence of the driven input is 1/2.

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 1.25µs

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.
