Overview

This analog-to-digital converter (ADC) is a one-channel SAR ADC with multi-input PGA and bandgap. It is devised to replace the sigma-delta ADC used in audio CODEC. The multi inputs refer to Microphone in, FM in and Line in. All inputs have 24dB gain in 16 steps, but for Microphone in, it has an additional 20dB gain boost.
