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