SC324ADR2G Equivalent & Substitute Parts

Part Overview

The SC324ADR2G is a general-purpose operational amplifier integrated circuit containing four independent amplifier circuits in a 14-SOIC surface mount package. This device is manufactured by onsemi and is classified as obsolete. The SC324ADR2G operates across a wide supply voltage range of 3 V to 32 V and delivers 40 mA output current per channel, making it suitable for general-purpose analog signal processing applications.

Due to its obsolete product status, locating SC324ADR2G units from original inventory sources presents supply chain challenges. Identifying equivalent substitute parts with matching electrical and mechanical specifications ensures design continuity and maintains system performance in applications currently utilizing this component.
