LTC1288CS8#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1288CS8#TRPBF is a 3V micropower, 12-bit successive approximation sampling analog-to-digital converter in an 8-pin SO package. It features a software-selectable two-channel multiplexer and operates on a single supply from 2.7V to 6V. The device typically draws 210μA at 6.6ksps and powers down to 1nA when inactive. Key electrical parameters include a maximum differential nonlinearity of 0.75 LSB, a signal-to-noise plus distortion ratio of 67 dB, and a spurious-free dynamic range of 88 dB. It utilizes a serial interface compatible with SPI and Microwire protocols.
