LM324 SMD IC – Quad Operational Amplifier 3V-32V Supply, SMD Package (Surface-Mount)

Description

The LM324 SMD IC is a versatile, high-value integrated circuit that brings four independent operational amplifiers (op-amps) into a single surface-mount package. Designed for modern electronics where space is at a premium and high flexibility is required, this chip opens up a wide range of possibilities—from power supply circuits to sensor interfaces and audio amplification.

✅ Key Features

• Single-supply operation from 3.0 V to 32 V (or dual ± supplies in some versions). onsemi+2Mouser Electronics+2

• Four amplifiers per package, enabling compact but powerful multi-channel designs. Texas Instruments

• Input common-mode voltage includes ground, meaning the op-amps can sense voltages down to the negative supply line. Mouser Electronics+1

• Short-circuit protected outputs, improving robustness in practical circuits. onsemi

• Low cost and widely available in SMD formats—ideal for hobby and industrial designs alike. componentstree.com+1
