The LM321MF/NOPB is a low-power, single-channel operational amplifier (op-amp) from Texas Instruments (TI), designed for space-constrained and battery-operated applications. It is housed in a compact 5-pin SOT-23 package, offering a balance of performance and efficiency for a wide range of systems.

Key features include:

• Wide supply voltage range: Operates from 3 V to 32 V, supporting both single-supply (e.g., 3–5 V) and dual-supply (±1.5 V to ±15 V) configurations.
• Low power consumption: Draws only 430 µA of quiescent current, ideal for battery-powered devices.
• High performance: Features a 1 MHz gain-bandwidth product, 0.4 V/µs slew rate, and 65 dB common-mode rejection ratio (CMRR), ensuring reliable signal amplification.
• Stability with capacitive loads: Can drive high-capacitive loads without oscillation.
• Precision: Includes a low input bias current (45 nA) and input offset voltage (2 mV), suitable for precision applications.

Applications span signal conditioning, sensor interfaces, industrial control, portable electronics, and communication systems. Its compact footprint, wide voltage tolerance, and robust performance make it a versatile choice for embedded systems where space and power efficiency are critical. The LM321MF/NOPB is also compatible with harsh environments, operating across a -40°C to 125°C temperature range.
