# LM324QT (Component)

## Description

Quad Operational Amplifier IC – The STMicroelectronics LM324QT integrates four independent, internally frequency\-compensated op\-amps for analog signal conditioning, amplification, filtering, and sensor interfaces\. It operates from a 3 V to 30 V single supply or ±1\.5 V to ±15 V dual supplies, with a 1\.3 MHz gain\-bandwidth product, 100 dB typical voltage gain, and 20 nA typical input bias current\. The device features an input common\-mode range that includes ground and is housed in a 16\-pin QFN \(3 × 3 mm\) package\.
