Basic Properties
Product Description
The LM321A/358A/324A series from 3PEAK consists of high-voltage, general-purpose operational amplifiers designed to offer a stable frequency response with low power consumption and low offset voltage. Utilizing 3PEAK's proprietary design techniques, these amplifiers deliver a 0.9MHz bandwidth, a $0.5V/mu s$ slew rate, and excellent EMI suppression performance (71dB at 1GHz), all while drawing a mere 100µA quiescent current per channel.
Acting as cost-effective, plug-in replacements for industry-standard commercially available op-amps, this family significantly reduces power dissipation while enhancing input/output dynamic range and performance in demanding applications.
