mono 10bit SAR ADC

Overview

This analog-to-digital converter (ADC) uses successive approximation register (SAR) architecture to reach 10-bit resolution. The ADC includes internal sample/hold circuits, a capacitive DAC, a comparator, and logic control circuits. An external reference voltage is needed. It is particularly suited for integrated auxiliary codec applications and multi-converter architectures in wireless or battery-operated products. There are 2 input channels, selected by analog input MUX with control signal.
