The LMP2234 is a quad micropower precision amplifier designedfor battery powered applications. The 1.8 to 5.5Voperating voltage range and quiescent power consumption ofonly 62 μW extend the battery life in portable systems. TheLMP2234 is part of the LMP® precision amplifier family. Thehigh impedance CMOS input makes it ideal for instrumentationand other sensor interface applications.The LMP2234 has a maximum offset voltage of 150 μV and0.3 μV/°C offset drift along with low bias current of only±20 fA. These precise specifications make the LMP2234 agreat choice for maintaining system accuracy and long termstability.The LMP2234 has a rail-to-rail output that swings 15 mV fromthe supply voltage, which increases system dynamic range.The common mode input voltage range extends 200 mV belowthe negative supply, thus the LMP2234 is ideal for groundsensing in single supply applications.The LMP2234 is offered in 14-Pin SOIC and TSSOP packages.
