Description

LM321MX/MFX (A63A) Low Power Op-Amp IC – SOT-23-5 SMD Package

The LM321MX/MFX (A63A) is a versatile, single-channel, low-power operational amplifier (op-amp) designed for compact, cost-sensitive applications. Housed in a space-saving SOT-23-5 surface-mount package, it provides rail-to-rail output swing, stable operation across a wide supply range, and is ideal for portable and battery-powered devices.

The LM321 offers low supply current, high gain-bandwidth, and wide input common-mode voltage, making it a suitable choice for signal conditioning, filtering, and buffering in analog and mixed-signal circuits.
