LMC6492 Dual/LMC6494 Quad

CMOS Rail-to-Rail Input and Output Operational

Amplifier

General Description

Features

The LMC6492/LMC6494 amplifiers were specifically devel-

oped for single supply applications that operate from −40˚C

to +125˚C. This feature is well-suited for automotive systems

because of the wide temperature range. A unique design to-

pology enables the LMC6492/LMC6494 common-mode volt-

age range to accommodate input signals beyond the rails.

This eliminates non-linear output errors due to input signals

(Typical unless otherwise noted)

n Rail-to-Rail input common-mode voltage range,

guaranteed over temperature

n Rail-to-Rail output swing within 20 mV of supply rail,

100 kΩ load

n Operates from 5V to 15V supply

n Excellent CMRR and PSRR 82 dB

n Ultra low input current 150 fA

n High voltage gain (R_L100 kΩ) 120 dB

n Low supply current ( V_S5V) 500 µA/Amplifier

n Low offset voltage drift 1.0 µV/˚C

exceeding

a traditionally limited common-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 complemented

by rail-to-rail output swing. This assures maximum dynamic

signal range which is particularly important in 5V systems.

Applications

n Automotive transducer amplifier

n Pressure sensor

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

provide high accuracy and direct interfacing with high imped-

ance sources.

n Oxygen sensor

n Temperature sensor

n Speed sensor
