LTC1197IS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1197IS8#TRPBF is a 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It features a single differential or single-ended analog input and an external reference pin. The device operates on a single supply voltage ranging from 4V to 9V with a maximum sampling rate of 500ksps. Typical power dissipation is 25mW at full speed operation. It utilizes a 3-wire serial interface compatible with SPI and Microwire protocols, housed in an 8-lead SOIC package.
