LMC6062

Precision CMOS Dual Micropower Operational Amplifier

General Description

The LMC6062 is a precision dual low offset voltage, mi-

cropower operational amplifier, capable of precision single

supply operation. Performance characteristics include ultra

low input bias current, high voltage gain, rail-to-rail output

swing, and an input common mode voltage range that in-

cludes ground. These features, plus its low power consump-

tion, make the LMC6062 ideally suited for battery powered

applications.

Other applications using the LMC6062 include precision

full-wave rectifiers, integrators, references, sample-and-hold

circuits, and true instrumentation amplifiers.

This device is built with National’s advanced double-Poly

Silicon-Gate CMOS process.

For designs that require higher speed, see the LMC6082

precision dual operational amplifier.
