LMC662

CMOS Dual Operational Amplifier

General Description

The LMC662 CMOS Dual 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

broadband noise as well as voltage gain into realistic loads

(2 k

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

cepted bipolar equivalents.

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

Silicon-Gate CMOS process.

See the LMC660 datasheet for a Quad CMOS operational

amplifier with these same features.
