AVDD1 and AVSS power the precharge buffers and the internal sampling switches. The ADC can be configured either for bipolar input operation (such as using ±2.5-V power supplies), or for unipolar input operation (such as AVDD1 = 5 V and AVSS = DGND). Use a parallel combination of 1-µF and 0.1-µF bypass capacitors across the AVDD1 supply voltage and the AVSS pin, with a 3-Ω series resistor placed in series between the capacitors and the AVDD1 pin. Place the resistor and capacitors as close as possible to the AVDD1 pin.
