ADVANCE INFORMATION
AVDD1 and AVSS are analog supply voltages that power the precharge buffers and the modulator sampling switches. Configure the ADC for bipolar operation (such as ±2.5V power supplies), or for unipolar operation (such as AVDD1 = 5V and AVSS = DGND). The mid- and low-speed operating modes offer the option of reducing AVDD1. See the Specifications section for details.
