LM324 SMD Quad Operational Amplifier (SOIC-14) 🔧

The LM324 is a quad operational amplifier in a compact SOIC-14 surface-mount package, designed for reliable single-supply analog signal processing. With its wide supply voltage range (3 V to 32 V), low power consumption, and internal frequency compensation for stable operation, this IC is a versatile choice for engineers and makers building analog front-ends for Arduino, Raspberry Pi, and other microcontroller-based systems. It’s ideal for precision amplification, active filtering, and general electronics components prototyping.

Key Features ⚙️
