Description

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 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.

Applications
•Precision instrumentation amplifiers
•Battery powered medical instrumentation

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
