FEATURES

DESCRIPTION

The LMC6492/LMC6494 amplifiers were specifically

2

(Typical Unless Otherwise Noted)

developed for single supply applications that operate

•

Rail-to-Rail Input Common-Mode Voltage

from

−40°C to +125°C. This feature is well-suited for

Range, Ensured Over Temperature

automotive systems because of the wide temperature

•

Rail-to-Rail Output Swing within 20 mV of

range.

A

unique

design

topology

enables

the

LMC6492/LMC6494 common-mode voltage range to

Supply Rail, 100 k

Ω Load

accommodate input signals beyond the rails. This

•

Operates from 5V to 15V Supply

eliminates non-linear output errors due to input

•

Excellent CMRR and PSRR 82 dB

signals exceeding a traditionally limited common-

•

Ultra Low Input Current 150 fA

mode voltage range. The LMC6492/LMC6494 signal

range has a high CMRR of 82 dB for excellent

•

accuracy in non-inverting circuit configurations.

•

The

LMC6492/LMC6494

rail-to-rail

input

is

μA/Amplifier

complemented

by

rail-to-rail

output

swing.

This

•

Low Offset Voltage Drift 1.0

μV/°C

assures maximum dynamic signal range which is

particularly important in 5V systems.

APPLICATIONS

Ultra-low input current of 150 fA and 120 dB open

•

Automotive Transducer Amplifier

loop gain provide high accuracy and direct interfacing

•

Pressure Sensor

with high impedance sources.

•

Oxygen Sensor

•

Temperature Sensor
