LMP2234 Quad

Micropower, Precision, RRO Amplifier with CMOS Input

General Description

Features

The LMP2234 is a quad micropower precision amplifier de-

signed for battery powered applications. The 1.8 to 5.5V

operating voltage range and quiescent power consumption of

only 62 μW extend the battery life in portable systems. The

LMP2234 is part of the LMP^®precision amplifier family. The

high impedance CMOS input makes it ideal for instrumenta-

tion and other sensor interface applications.

The LMP2234 has a maximum offset voltage of 150 μV and

0.3 μV/°C offset drift along with low bias current of only

±20 fA. These precise specifications make the LMP2234 a

great choice for maintaining system accuracy and long term

stability.

58 V/ms

60 nV/√Hz

–40°C to 125°C

The LMP2234 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 LMP2234 is ideal for ground

sensing in single supply applications.

Applications

Precision instrumentation amplifiers

■

The LMP2234 is offered in 14-Pin SOIC and TSSOP pack-

ages.

Battery powered medical instrumentation

High impedance sensors

■

Strain gauge bridge amplifier

Thermocouple amplifiers
