µPC812, 4092 are unique J-FET input dual operational amplifiers 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. Depending on the operating ambient temperature, µPC812 is suitable to communication application while µPC4092 is for general-purpose usage. In addition to this series of line-up, single channel type operational amplifier, µPC811, 4091 with the same circuit configuration are also available.
