LMP7731  
2.9 nV/sqrt(Hz) Low Noise, Precision, RRIO, Operational  
Amplifier in SOT23-5  
General Description  
The LMP7731 is a single, low noise, low offset voltage, rail-  
to-rail input and output, low voltage precision amplifier. The  
LMP7731 is part of the LMP® precision amplifier family and is  
ideal for precision and low noise applications with low voltage  
requirements.

This operational amplifier offers low voltage noise of 2.9 nV/  
with a 1/f corner of only 3 Hz and low DC offset with a  
maximum value of ±40 µV, targeting high accuracy, low fre-  
quency applications. The LMP7731 has bipolar input stages  
with a bias current of only 1.5 nA. This low input bias current,  
complemented by the very low AC and DC levels of voltage  
noise, makes the LMP7731 an excellent choice for photom-  
etry applications.

±1.5 nA  
The LMP7731 provides a wide GBW of 22 MHz while con-  
suming only 2 mA of current. This high gain bandwidth along  
with the high open loop gain of 130 dB enables accurate sig-  
nal conditioning in applications with high closed loop gain  
requirements.  
5-Pin SOT23 package  
The LMP7731 has a supply voltage range of 1.8V to 5.5V,  
making it an ideal choice for battery operated portable appli-  
cations.  
Applications  
Thermopile amplifier  
The LMP7731 is offered in a 5-pin SOT23 package.  
Gas analysis instruments  
Photometric instrumentation  
Medical instrumentation
