Description
LM324 & LM358 Operational Amplifiers | DIP/SMD Variants Available
Low-Power Operational Amplifier ICs (Op-Amps) are high-performance, energy-efficient analog components designed for signal conditioning, filtering, or other amplification tasks where battery life and low energy consumption are critical. These Op-Amps maintain excellent accuracy and stability while consuming very little current, making them ideal for portable, battery-operated devices, medical instruments, sensor interfaces, and wireless systems.
