LTC1289 - 3 Volt Single Chip 12-Bit Data Acquisition System
LTC1289 - 3 Volt Single Chip 12-Bit Data Acquisition System - Linear Technology（凌力尔特）
The LTC1289 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, or 11-bit plus sign bipolar A/D conversion. The 8 channel input multiplexer can be configured for either single-ended or differential inputs (or combinations thereof). An on-chip sample and hold is included for all single-ended input channels. When the LTC1289 is idle it can be powered down in applications where low power consumption is desired.
The serial I/O is designed to be compatible with industry standard full duplex serial interfaces. It allows either MSB- or LSB- first data and automatically provides 2’s complement output coding in the bipolar mode. The output data word can be programmed for a length of 8, 12 or 16 bits. This allows easy interface to shift registers and a variety of processors.
