The LMP2231 is a single micropower high precision amplifier designed for battery-powered applications. The 1.6V to 5.5V operating supply voltage range and quiescent power consumption of only 16μW extend battery life in portable battery-powered systems. The LMP2231 is part of the LMP family of high precision amplifiers. High impedance CMOS inputs, ideal for instrumentation and other sensor interface applications.
The LMP2231 has a maximum offset voltage drift of ± of 150 μV and only 0.4 μV/°C to offset the low bias current of only 20 FA. 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 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 LMP2231 ideal for use in single-supply applications and terrestrial remote sensing.
The LMP2231 is available in 5-pin SOT23 and 8-pin SOIC packages.
Dual and quad versions of this product are also available. Dual, the LMP2232 offers an 8-pin SOIC and MSOP. Fourth, the LMP2234 offers a 14-pin SOIC and TSSOP.
