LMP2234 is a four-channel micro-power high-precision amplifier designed for battery-powered applications. The 1.6 to 5.5V operating supply voltage range and quiescent power consumption of only 50μW extend the battery life of portable systems. LMP2234 is part of LMP's range of high-precision amplifiers. Ideal for high-impedance CMOS inputs, instrumentation, and other sensor interface applications.
LMP2234 maximum offset voltage of 150 μV, offset drift of 0.3 μV/°C, and low bias are currently only available ± 20 FA 。 These precise specifications make LMP2234 a great choice for maintaining system accuracy and long-term stability.
LMP2234 has a rail-to-rail output swing from the supply voltage, which increases the dynamic range of the system to 15 mV. The common-mode input voltage range is extended by 200 mV below the negative supply, making it ideal LMP2234 for ground remote sensing in single-supply applications.
LMP2234 is available in 14-pin SOIC and TSSOP packages.
