Single Chip 10-Bit Data  
Acquisition System

FEATURES  
DESCRIPTIO  
The LTC®1090 is a data acquisition component which  
contains a serial I/O successive approximation A/D con-  
verter. It uses LTCMOSTM switched capacitor technology  
to perform either 10-bit unipolar, or 9-bit plus sign bipolar  
A/D conversions. 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.  
Software Programmable Features:  
Unipolar/Bipolar Conversions  
4 Differential/8 Single Ended Inputs  
MSB or LSB First Data Sequence  
Variable Data Word Length  
Built-In Sample and Hold  
Single Supply 5V, 10V or ±5V Operation  
Direct 4 Wire Interface to Most MPU Serial Ports and  
All MPU Parallel Ports  
30kHz Maximum Throughput Rate  
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, 10,  
12 or 16 bits. This allows easy interface to shift registers  
and a variety of processors.

KEY SPECIFICATIO S  
Resolution: 10 Bits  
Total Unadjusted Error (LTC1090A): ±1/2LSB Max  
Conversion Time: 22µs  
The LTC1090A is specified with total unadjusted error  
(including the effects of offset, linearity and gain errors)  
less than ±0.5LSB.  
Supply Current: 2.5mA Max, 1.0mA Typ

TheLTC1090isspecifiedwithoffsetandlinearitylessthan  
±0.5LSB but with a gain error limit of ±2LSB for  
applications where gain is adjustable or less critical.
