LT LTC1289BCSW#PBF

数据采集系统（DAS）812 b25k串行，并联±3.3V0°C ~ 70°C表面贴装型20-SOIC（0.295"，7.50mm 宽）

Overview

The LTC1289BCSW 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 LTC1289BCSW 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.
