LM358 OPAMP

The LM358 is a versatile and cost-effective dual operational amplifier (op-amp) designed for a wide range of analog signal processing applications. Featuring two independent, high-gain op-amps in a single package, the LM358 operates from a single power supply (3V–32V) or dual supplies (±1.5V–±16V), making it ideal for battery-powered and embedded systems.

Widely used in Arduino-based projects, signal conditioning circuits, sensor amplifiers, active filters, and audio pre-amplifiers, the LM358 offers stable performance, low power consumption, and easy integration into both hobbyist and industrial designs.
