LMC660

CMOS Quad Operational Amplifier

n Ultra low input bias current: 2 fA

n Input common-mode range includes V⁻

General Description

The LMC660 CMOS Quad operational amplifier is ideal for

operation from a single supply. It operates from +5V to +15V

and features rail-to-rail output swing in addition to an input

common-mode range that includes ground. Performance

limitations that have plagued CMOS amplifiers in the past

are not a problem with this design. Input V_OS, drift, and

broadband noise as well as voltage gain into realistic loads

(2 kΩ and 600Ω) are all equal to or better than widely ac-

cepted bipolar equivalents.

n Operating range from +5V to +15V supply

n I_SS375 µA/amplifier; independent of V

n Low distortion: 0.01% at 10 kHz

n Slew rate: 1.1 V/µs

n Available in extended temperature range (−40˚C to

+125˚C); ideal for automotive applications

n Available to Standard Military Drawing specification

This chip is built with National’s advanced Double-Poly

Silicon-Gate CMOS process.

Applications

n High-impedance buffer or preamplifier

n Precision current-to-voltage converter

n Long-term integrator

See the LMC662 datasheet for a dual CMOS operational

amplifier with these same features.

n Sample-and-Hold circuit

n Peak detector

n Medical instrumentation

n Industrial controls

Features

n Rail-to-rail output swing

n Specified for 2 kΩ and 600Ω loads

n High voltage gain: 126 dB

n Low input offset voltage: 3 mV

n Low offset voltage drift: 1.3 µV/˚C

n Automotive sensors
