and-holds. On-chip serial ports allow efficient data trans-  
fer to a wide range of microprocessors and microcontrol-  
lers. These circuits can provide a complete data acquisi-

FEATURES  
■
Programmable Features  
– Unipolar/Bipolar Conversions  
–
Differential/Single-Ended Multiplexer  
Configurations  
The high impedance analog inputs and the ability to  
operate with reduced spans (below 1V full scale) allow  
direct connection to sensors and transducers in many  
applications, eliminating the need for gain stages.  
■
■
■
Sample-and-Holds  
Single Supply 5V, 10V or ±5V Operation  
Direct 3- or 4-Wire Interface to Most MPU Serial  
Ports and All MPU Parallel I/O Ports  
Analog Inputs Common Mode to Supply Rails  
Resolution: 10 Bits  
Total Unadjusted Error (A Grade): ±1LSB Over Temp  
Fast Conversion Time: 20µs  
Low Supply Current  
■

■
■
■
An efficient serial port communicates without external  
hardware to most MPU serial ports and all MPU parallel  
I/O ports allowing eight channels of data to be transmitted  
over as few as three wires. This, coupled with low power  
consumption, makes remote location possible and facili-  
tates transmitting data through isolation barriers.  
LTC1091: 3.5mA Max, 1.5mA Typ  
LTC1092/LTC1093/LTC1094: 2.5mA Max, 1mA Typ  
Temperature drift of offset, linearity and full-scale error  
are all extremely low (1ppm/°C typically) allowing all  
grades to be specified with offset and linearity errors of  
±0.5LSB maximum over temperature. In addition, the A  
grade devices are specified with full-scale error and total  
unadjusted error (including the effects of offset, linearity  
and full-scale errors) of ±1LSB maximum over tempera-  
ture. The lower grade has a full-scale specification of  
±2LSB for applications where full scale is adjustable or  
less critical.

DESCRIPTIO  
The LTC®1091/LTC1092/LTC1093/LTC1094 10-bit data  
acquisition systems are designed to provide complete  
function, excellent accuracy and ease of use when digitiz-  
ing analog data from a wide variety of signal sources and  
transducers. Built around a 10-bit, switched capacitor,
