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,

successiveapproximationA/Dcore, thesedevices include
