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.

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.
