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 LTCMOS
TM 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
standard full duplex serial interfaces. It allows either MSB-
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.

FOR OVERVOLTAGE PROTECTION ON
ONLY ONE CHANNEL LIMIT THE INPUT
CURRENT TO 15mA. FOR MORE THAN
ONE CHANNEL LIMIT THE INPUT
CURRENT TO 7mA PER CHANNEL AND
28mA FOR ALL CHANNELS.
CONVERSION RESULTS ARE NOT VALID
WHEN THE SELECTED OR ANY OTHER
CHANNEL IS OVERVOLTAGED (VIN < V
or VIN > VCC).
