The LMP2234 is a quad micropower precision amplifier designed
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 instrumentation
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.
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.
The LMP2234 is offered in 14-Pin SOIC and TSSOP packages.
