LTC1287

The LTC1287 is a 3V data acquisition component whichcontains a serial I/O successive approximation A/D con-verter. The device specifications are guaranteed at asupply voltage of 2.7V. It uses LTCMOSTMswitched ca-pacitor technology to perform a 12-bit unipolar, A/Dconversion. The differential input has an on-chip sample-and-hold on the (+) input.

The serial I/O is designed to communicate without externalhardware to most MPU serial ports and all MPU parallelI/O ports allowing data to be transmitted and received overthree wires. The low voltage operating capability and thelow power consumption of this device make it ideallysuited for battery applications. Given the ease of use, smallpackage size and the minimum number of interconnectsfor I/O, the LTC1287 can be used for remote sensingapplications.
