DESCRIPTIO  
EATURE  
S
F
The LTC®1290 is a data acquisition component which  
contains a serial I/O successive approximation A/D con-  
verter. It uses LTCMOSTM switched capacitor technology  
toperformeither12-bitunipolaror11-bitplus signbipolar  
A/D conversions. The 8-channel input multiplexer can be  
configuredforeithersingle-endedordifferentialinputs (or  
combinations thereof). An on-chip sample-and-hold is  
included for all single-ended input channels. When the  
LTC1290 is idle it can be powered down with a serial word  
in applications where low power consumption is desired.

Software Programmable Features  
– Unipolar/Bipolar Conversion  
– Four Differential/Eight Single-Ended Inputs  
– MSB- or LSB-First Data Sequence  
– Variable Data Word Length  
– Power Shutdown  
Built-In Sample-and-Hold  
Single Supply 5V or ±5V Operation  
Direct Four-Wire Interface to Most MPU Serial Ports  
and All MPU Parallel Ports

50kHz Maximum Throughput Rate  
The serial I/O is designed to be compatible with industry  
standardfullduplexserialinterfaces. Itallows eitherMSB-  
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.
