LMC7101

Low-Power Operational Amplifier

General Description

The LMC7101 is a high-performance, low-power, operational

amplifier which is pin-for-pin compatible with the National

Semiconductor LMC7101. It features rail-to-rail input and

The LMC7101 is a 500kHz gain bandwidth amplifier de-

signed to operate from 2.7V to 12V single-ended power

supplies with guaranteed performance at supply voltages of

2.7V, 3V, 5V, and 12V.

This op amp’s input common-mode range includes ground

and extends 300mV beyond the supply rails. For example,

the common-mode range is –0.3V to +5.3V with a 5V supply.
