3 Volt Single Chip 12-Bit  
Data Acquisition System

FEATURES  
DESCRIPTIO  
The LTC®1289 is a 3V data acquisition component which  
contains a serial I/O successive approximation A/D con-  
verter. The device specifications are guaranteed at a  
supply voltage of 2.7V. It uses LTCMOSTM switched ca-  
pacitor 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  
standardfullduplexserialinterfaces. ItallowseitherMSB-  
or LSB- first data and automatically provides 2’s comple-  
ment 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.
