Overview

The LM321A/358A/324A series amplifiers are newest high supply voltage amplifiers with low offset, low power and stable frequency response. They incorporate 3PEAK’s proprietary and patented design techniques to achieve very good AC performance with 0.9MHz bandwidth, 0.5V/μs slew rate and maximum 3mV offset while drawing only 100μA of quiescent current per amplifier. The input common-mode voltage range extends to V–, and the outputs swing rail-to-rail. The LM321A/358A/324A family can be used as plug-in replacements for many commercially available op-amps to reduce power and improve input/output range and performance.

The combination of features makes the LM321A/358A/324A ideal choices for power module, industrial control, motor control and audio application.
