LMP2234 Quad  
Micropower, Precision, RRO Amplifier with CMOS Input  
General Description  
Features  
The LMP2234 is a quad micropower precision amplifier de-  
signed for battery powered applications. The 1.8 to 5.5V  
operating voltage range and quiescent power consumption of  
only 62 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 instrumenta-  
tion and other sensor interface applications.

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.  
58 V/ms  
60 nV/Hz  
–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 be-  
low the negative supply, thus the LMP2234 is ideal for ground  
sensing in single supply applications.  
Applications  
Precision instrumentation amplifiers  
The LMP2234 is offered in 14-Pin SOIC and TSSOP pack-  
ages.  
Battery powered medical instrumentation  
High impedance sensors  
Strain gauge bridge amplifier  
Thermocouple amplifiers  
Typical Application  
Strain Gauge Bridge Amplifier
