The LMP2234 is a quad micropower 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 battery life in portable systems. The LMP2234 is part of the LMP family of high precision amplifiers. High impedance CMOS inputs, ideal for instrumentation and other sensor interface applications.
The LMP2234 has a maximum offset voltage of 150μV, an offset drift of 0.3μV/°C, and a low bias that is currently only available ± 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 swing from the supply voltage, thereby increasing the dynamic range of the system to 15 mV. The common-mode input voltage range extends below 200 millivolts from negative supplies, making the LMP2234 ideal for ground-based remote sensing in single-supply applications.
The LMP2234 is available in 14-pin SOIC and TSSOP packages.
