LM324M

Instrumentation, Op Amps, Buffer Amps Overview

The LM324M is a quad operational amplifier manufactured by Texas Instruments, housed in a SOIC-14 package. It operates on a single supply voltage ranging from 3V to 32V or dual supplies of ±1.5V to ±16V. The device features four high-voltage amplifiers with a gain-bandwidth product of approximately 1MHz and a typical quiescent current of 500µA per amplifier. Input common-mode voltage includes ground, and outputs can swing to within 20mV of the negative rail.
