FEATURES  
DESCRIPTION  
The LMP2234 is  
a quad micropower precision  
23  
(For VS = 5V, Typical Unless Otherwise Noted)  
amplifier designed for battery powered applications.  
The 1.6 to 5.5V operating supply voltage range and  
quiescent power consumption of only 50 μW extend  
the battery life in portable systems. The LMP2234 is  
part of the LMP™ precision amplifier family. The high  
impedance CMOS input makes it ideal for

Supply Current at 1.8V 31 µA  
Operating Voltage Range 1.6V to 5.5V  
Low TCVOS ±0.75 µV/°C (max)  
VOS ±150 µV (max)  
Input Bias Current ±20 fA  
PSRR 120 dB

applications.  
and  
other  
sensor  
interface  
CMRR 97 dB  
The LMP2234 has a maximum offset voltage of 150  
μV and 0.3 μV/°C offset drift along with low bias  
current of only ±20 fA. These precise specifications  
make the LMP2234 a great choice for maintaining  
system accuracy and long term stability.  
Open Loop Gain 120 dB  
Gain Bandwidth Product 130 kHz  
Slew Rate 58 V/ms  
Input Voltage Noise, f = 1 kHz 60 nV/√Hz  
Temperature Range –40°C to 125°C  
The LMP2234 has a rail-to-rail output that swings 15  
mV from the supply voltage, which increases system  
dynamic range. The common mode input voltage  
range extends 200 mV below the negative supply,  
thus the LMP2234 is ideal for ground sensing in  
single supply applications.
