The LMP2234 is a quad micropower precision 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 instrumentation and other sensor interface
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.
