LMP2232 is a dual micro-power high-precision amplifier designed for battery-powered applications. The 1.6V to 5.5V operating supply voltage range and quiescent power consumption of only 26μW extend the battery life of portable systems. LMP2232 is part of LMP's range of high-precision amplifiers. Ideal for high-impedance CMOS inputs, instrumentation, and other sensor interface applications.
LMP2232 has a maximum offset voltage of 150μV and a low bias current of only ± 20 FA and a maximum offset voltage drift of only 0.5μV/°C. These precise specifications make LMP2232 a great choice for maintaining system accuracy and long-term stability.
LMP2232 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 millivolts below the negative supply, making it ideal LMP2232 for ground remote sensing in single-supply applications.
LMP2232 is available in 8-pin SOIC and MSOP packages.
LMP2231 is a single version of this product and LMP2234 is a four-channel version of this product. Both products are available on the website of National Semiconductor.
