Texas Instruments LMP2231 Single Micropower, 1.6V, Precision Operational Amplifier with CMOS Inputs LMP2231AMA/NOPB

The LMP2231AMA/NOPB is a single micropower precision operational amplifier designed for battery-powered applications, operating within a supply voltage range of 1.6V to 5.5V. It features a low supply current of 10 ¬µA, which contributes to extended battery life. The amplifier has a maximum input offset voltage of ¬±150 ¬µV and a temperature coefficient of offset voltage drift of ¬±0.4 ¬µV/¬8C for the LMP2231A variant, ensuring high accuracy and stability over temperature variations. With a common mode rejection ratio (CMRR) of 97 dB and a power supply rejection ratio (PSRR) of 120 dB, the LMP2231 maintains performance in varying conditions. The device supports rail-to-rail output, allowing it to swing within 15 mV of the supply rails, which enhances its utility in single-supply applications. It is available in both 5-Pin SOT-23 and 8-Pin SOIC packages, making it suitable for compact designs. The operational temperature range is specified from -40¬8C to 125¬8C, accommodating a variety of environmental conditions. This operational amplifier is ideal for precision instrumentation, medical instrumentation, and sensor interface applications.
