Overview
Description
µPC811 is a unique J-FET input operational amplifier that uses a high-speed PNP transistor (fT = 300 MHz)for the output stage to achieve fast response and high stability. The resistor-trimming method proven in other Renesas High-Precision Op-Amp and High-Precision reference voltage is incorporate in this Op-Amp input stage, thus producing an excellent low offset voltage characteristics that has surpasses conventional general purpose op-amp in spite of being JFET input. Along with this series of lineup, the dual type operational amplifier, μPC812 and 4092 with the same circuit configuration are also available.
