LMC6034

CMOS Quad Operational Amplifier

General Description

The LMC6034 is a CMOS quad operational amplifier which

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

performance features include an input common-mode range

that reaches ground, low input bias current, and high voltage

gain into realistic loads, such as 2 k

Ω and 600Ω.

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

Silicon-Gate CMOS process.

See the LMC6032 datasheet for a CMOS dual operational

amplifier with these same features. For higher performance

characteristics refer to the LMC660.
