LMV931MFX/NOPB Description

The LMV931MFX/NOPB from Texas Instruments is a single-channel, low-power operational amplifier designed for precision applications requiring rail-to-rail input/output (RRIO) performance. Operating from a single supply voltage (1.8V to 5.5V), it delivers low quiescent current (116 µA typical) and high efficiency, making it ideal for battery-powered and portable devices. Built on BiCMOS process technology, it offers a 1.5 MHz gain bandwidth product (GBP), 113 dB voltage gain, and low input noise (50 nV/√Hz), ensuring high accuracy in signal conditioning. The CMOS output stage provides robust drive capability (65 mA typical output current), while its small SOT-23-5 package (2.92 mm × 1.6 mm × 1.02 mm) saves board space.

LMV931MFX/NOPB Features

• Rail-to-Rail I/O: Ensures maximum dynamic range in low-voltage applications.
• Low Power Consumption: 0.21 mA max supply current extends battery life.
• High Precision: 4 mV max input offset voltage, 50 dB min CMRR, and 75 dB min PSRR enhance signal integrity.
• Robust Performance: 0.42 V/µs slew rate and 1.5 MHz GBP suit bandwidth-sensitive designs.
• Compact & Reliable: 5-pin SOT-23 package with RoHS compliance for space-constrained applications.
• Wide Temperature Range: Operates from -40°C to +125°C, ideal for industrial environments.
