LMP2231 Datasheet (National Semiconductor) - Precision Operational Amplifier

LMP2231, Precision Operational Amplifier

The LMP2231 is a single micropower precision amplifier designed for battery powered applications.

The 1.8V to 5.0V guaranteed supply voltage range and quiescent power consumption of only 18 μW extend the battery life in portable battery operated systems.

The LMP2231 is part of the LMP® precision amp
