Overview
The LM321MF, produced by Texas Instruments, is a low-power, single-channel operational amplifier designed to bring performance and economy to low-power systems. It features a high unity gain frequency and a specified 0.4-V/µs slew rate, making it suitable for a wide range of applications. The LM321MF operates with a quiescent current of only 430 µA per amplifier at 5 V, and its input common mode range includes ground, allowing it to function in both single and dual supply configurations. It is available in the compact SOT-23 package, making it ideal for applications where board space is limited.
