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
output performance in Micrel’s IttyBitty™ SOT-23-5 package.

The LMC7101 is a 500kHz gain bandwidth amplifier de­signed 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.
