NEC uPC4741 Quad Operational Amplifier Datasheet
This document is a technical datasheet for the NEC uPC4741, a bipolar analog integrated circuit consisting of four independent frequency compensated operational amplifiers. It is designed for AC signal amplifier applications such as active filters or pulse amplifiers, offering higher speed and broader bandwidth than general purpose types like the 741.
The document provides comprehensive electrical characteristics including input offset voltage, bias current, slew rate, and common mode rejection ratio under various conditions. It also includes absolute maximum ratings, recommended operating conditions, typical performance curves, and detailed mechanical drawings for both the 14-pin plastic DIP (uPC4741C) and 14-pin plastic SOP (uPC4741G2) packages.
