130 kHz gain-bandwidth, 10 µA supply — precision for low-frequency sensor chains
The LMP2231AMF/NOPB is a single-channel general-purpose op-amp from TI's LMP® and PowerWise® series, offering a gain-bandwidth product of 130 kHz with a supply current of just 10 µA. That combination targets battery-powered or loop-powered applications where the signal bandwidth stays below a few kilohertz — think thermocouple amplifiers, strain-gauge bridges, or photodiode front-ends where the dominant noise is 1/f, not the op-amp's own thermal floor.
0.02 pA input bias, 10 µV offset — what it means for your sensor interface
Output current is rated 30 mA per channel — enough to drive a reference input or a small resistive load, but not intended for heavy analog output stages. No separate positive and negative supplies are needed.
SOT-23-5 package and temperature grade
Housed in a SOT-23-5 (SC-74A) package, the LMP2231AMF/NOPB occupies minimal board area — about 3 mm × 3 mm — and is suitable for compact sensor modules or portable instruments.
