LMP2231 is a single 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 16μW extend battery life in portable battery-powered systems. LMP2231 is part of LMP's range of high-precision amplifiers. Ideal for instrumentation and other sensor interface applications with high impedance CMOS inputs.
LMP2231 has a maximum ± of 150μV, a maximum offset voltage drift offset of only 0.4μV/°C, and a low bias current of only 20 FA. These precise specifications make LMP2231 a great choice for maintaining the accuracy and long-term stability of the system.
LMP2231 has a rail-to-rail output swing from the supply voltage, thus increasing the dynamic range of the system to 15 mV. The common-mode input voltage range is 200 mV lower than that of a negative supply, making it LMP2231 ideal for single-supply applications with ground induction.
LMP2231 is available in a 5-pin SOT23 package and an 8-pin SOIC package.
Dual and quad versions of this product are also available. Dual, LMP2232 provide 8-pin SOIC and MSOP. Four, LMP2234 offers 14-pin SOIC and TSSOP.
