LMC6022

Low Power CMOS Dual Operational Amplifier

General Description

The LMC6022 is a CMOS dual operational amplifier which

can operate from either a single supply or dual supplies. Its

performance features include an input common-mode range

that reaches V

100k and 5 k

Ω loads) that is equal to or better than widely

accepted bipolar equivalents, while the power supply re-

quirement is less than 0.5 mW.

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

Silicon-Gate CMOS process.

See the LMC6024 datasheet for a CMOS quad operational

amplifier with these same features.
