Overview
The LM321MF/NOPB, produced by Texas Instruments, is a low power, single operational amplifier designed to bring performance and economy to low power systems. It operates with a high unity gain frequency and a specified 0.4-V/µs slew rate, making it suitable for a wide range of applications. The amplifier can function with either a single or dual power supply voltage and includes true-differential inputs, allowing it to remain in the linear mode with an input common-mode voltage of 0 VDC. This versatility makes it ideal for both single supply and dual supply applications.
