The LTC1287 is a 3V data acquisition component which contains a serial I/O successive approximation A/D converter. The device specifications are guaranteed at a supply voltage of 2.7V. It uses LTCMOS™ switched capacitor technology to perform a 12-bit unipolar, A/D conversion. The differential input has an on-chip sample-and- hold on the (+) input.
The serial I/O is designed to communicate without external hardware to most MPU serial ports and all MPU parallel I/O ports allowing data to be transmitted and received over three wires. The low voltage operating capability and the low power consumption of this device make it ideally suited for battery applications. Given the ease of use, small package size and the minimum number of interconnects for I/O, the LTC1287 can be used for remote sensing applications.
