LMP2231AMFE/NOPB

The LMP2231AMFE/NOPB is a single MicroPower precision Operational Amplifier with CMOS inputs. It is designed for battery powered applications. The 1.6 to 5.5V operating supply voltage range and quiescent power consumption of only 16μW extend the battery life in portable battery operated systems. The LMP2231 is part of the LMP precision amplifier family. The high impedance CMOS input makes it ideal for instrumentation and other sensor interface applications. The LMP2231 has a maximum offset of 150µV and maximum offset voltage drift of only 0.4µV/°C along with low bias current of only ±20fA. These precise specifications make the LMP2231 a great choice for maintaining system accuracy and long term stability. The LMP2231 has a rail-to-rail output that swings 15mV from the supply voltage, which increases system dynamic range. The common mode input voltage range extends 200mV below the negative supply, thus the LMP2231 is ideal for use in single supply applications with ground sensing.
