LM324PT

Instrumentation, Op Amps, Buffer Amps Overview

The LM324PT is a quad operational amplifier manufactured by ROHM Semiconductor, belonging to the LM324 series. It features four independent high-gain amplifiers with internal frequency compensation. The device operates from a single power supply ranging from 3 V to 32 V or dual supplies of ±1.5 V to ±16 V. Key electrical specifications include a gain-bandwidth product of 800 kHz, a slew rate of 300 mV/µs, and an input bias current of 20 nA. It supports ground sensing input voltage ranges and delivers up to 30 mA output current per channel. The component is housed in a TSSOP-14 package suitable for surface mount technology.
