FEATURES  
DESCRIPTION  
The LMP7731 is a single, low noise, rail-to-rail input  
and output, 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.  
23  
(Typical Values, TA = 25°C, VS = 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  
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  
photometry applications.  
Open Loop Gain 130 dB  
GBW 22 MHz  
Slew Rate 2.4 V/µs  
THD @ f = 10 kHz, AV = +1, RL = 2 k0.001%  
Supply Current per Channel 2.2 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 LMP7731 provides a wide GBW of 22 MHz while  
consuming only 2 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 LMP7731 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 LMP7731 is offered in the space saving 5-Pin  
SOT-23 and 8-Pin SOIC packages.
