LMP2232 Dual

Micropower, 1.6V, Precision, Operational Amplifier with

CMOS Input

General Description

The LMP2232 is a dual micropower precision amplifier de-

signed for battery powered applications. The 1.6V to 5.5V

operating supply voltage range and quiescent power con-

sumption of only 26 μW extend the battery life in portable

systems. The LMP2232 is part of the LMP^®precision amplifier

family. The high impedance CMOS input makes it ideal for

instrumentation and other sensor interface applications.

The LMP2232 has a maximum offset voltage of 150 μV and

maximum offset voltage drift of only 0.5 μV/°C along with low

bias current of only ±20 fA. These precise specifications make

the LMP2232 a great choice for maintaining system accuracy

and long term stability.

58 V/ms

60 nV/√Hz

–40°C to 125°C

The LMP2232 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 LMP2232 is ideal for ground

sensing in single supply applications.

Applications

Precision instrumentation amplifiers

■
