LMP2231 Single

Micropower, 1.8V, Precision Operational Amplifier with

CMOS Inputs

General Description

The LMP2231 is a single micropower precision amplifier de-

signed for battery powered applications. The 1.8V to 5.0V

guaranteed supply voltage range and quiescent power con-

sumption of only 18 μW extend the battery life in portable

battery operated systems. The LMP2231 is part of the

LMP^®precision amplifier family. The high impedance CMOS

input makes it ideal for instrumentation and other sensor in-

terface applications.

The LMP2231 has a maximum offset of 150 µV and maximum

offset voltage drift of only 0.4 µV/°C along with low bias cur-

rent of only ±20 fA. These precise specifications make the

LMP2231 a great choice for maintaining system accuracy and

long term stability.

58 V/ms

60 nV/√Hz

–40°C to 125°C

The LMP2231 has a rail-to-rail output that swings 15 mV from

the supply voltage, which increases system dynamic range.

The common mode input voltage range extends 200 mV be-

low the negative supply, thus the LMP2231 is ideal for use in

single supply applications with ground sensing.

Applications
