LMP7731  
2.9 nV/sqrt(Hz) Low Noise, Precision, RRIO Amplifier  
General Description  
Features  
The LMP7731 is a single, low noise, rail-to-rail input and out-  
put, low voltage amplifier. The LMP7731 is part of the LMP®  
precision amplifier family and is ideal for precision and low  
noise applications with low voltage requirements.  
(Typical values, TA = 25°C, VS = 5V)  
Input voltage noise  
f = 3 Hz  
3.3 nV/Hz  
2.9 nV/Hz  
130 dB  
f = 1 kHz  
This operational amplifier offers low voltage noise of 2.9 nV/  
Hz with a 1/f corner of only 3 Hz. 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 level of voltage  
noise, makes the LMP7731 an excellent choice for photom-  
etry applications.

RRIO  
2.2 mA  
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.  
1.8V to 5.5V  
−40°C to 125°C  
±1.5 nA  
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  
Gas analysis instruments  
The LMP7731 is offered in the space saving 5-Pin SOT-23  
and 8-Pin SOIC packages.
