LMP2234 Quad Micropower, 1.6V, Precision, Operational Amplifier with CMOS Input

Check for Samples: LMP2234

FEATURES

DESCRIPTION

The LMP2234 is

a quad micropower precision

(For V_S= 5V, Typical Unless Otherwise Noted)

amplifier designed for battery powered applications.

The 1.6 to 5.5V operating supply voltage range and

quiescent power consumption of only 50 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

Supply Current at 1.8V 31 µA

Operating Voltage Range 1.6V to 5.5V

Low TCV_OS±0.75 µV/°C (max)

V_OS±150 µV (max)

Input Bias Current ±20 fA

PSRR 120 dB

instrumentation

applications.

and

other

sensor

interface

CMRR 97 dB

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.

Open Loop Gain 120 dB

Gain Bandwidth Product 130 kHz

Slew Rate 58 V/ms

Input Voltage Noise, f = 1 kHz 60 nV/√Hz

Temperature Range –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 below the negative supply,

thus the LMP2234 is ideal for ground sensing in

single supply applications.

APPLICATIONS

•
