2.9 nV/sqrt(Hz) Low Noise, RRIO Amplifier

Check for Samples: LMP7732

FEATURES

DESCRIPTION

The LMP7732 is a dual low noise, rail-to-rail input

and output, low voltage amplifier. The LMP7732 is

part of the LMP™ amplifier family and is ideal for

precision and low noise applications with low voltage

requirements.

•

(Typical Values, T_A= 25°C, V_S= 5V)

Input Voltage Noise

•

–

f = 3 Hz 3.3 nV/√Hz

f = 1 kHz 2.9 nV/√Hz

•

CMRR 130 dB

This operational amplifier offers low voltage noise of

2.9 nV/√Hz with a 1/f corner of only 3 Hz. The

LMP7732 has bipolar junction input stages with a

bias current of only 1.5 nA. This low input bias

current, complemented by the very low level of

voltage noise, makes the LMP7732 an excellent

choice for photometry applications.

Open Loop Gain 130 dB

GBW 22 MHz

Slew Rate 2.4 V/µs

THD 0.001% @ f = 10 kHz, AV = 1, RL = 2 kΩ

Supply Current 4.4 mA

Supply Voltage Range 1.8V to 5.5V

Operating Temperature Range −40°C to 125°C

Input Bias Current ±1.5 nA

RRIO

The LMP7732 provides a wide GBW of 22 MHz while

consuming only 4 mA of current. This high gain

bandwidth along with the high open loop gain of 130

dB enables accurate signal conditioning in

applications with high closed loop gain requirements.

The LMP7732 has a supply voltage range of 1.8V to

5.5V, making it an ideal choice for battery operated

portable applications.

APPLICATIONS

•

Gas Analysis Instruments

Photometric Instrumentation

Medical Instrumentation

The LMP7732 is offered in the 8-Pin SOIC and

VSSOP packages.

The LMP7731 is the single version of this product

and is offered in the 5-Pin SOT-23 and 8-Pin SOIC

packages.
