UPC4091 Overview
DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC4091 J-FET INPUT LOW-OFFSET OPERATIONAL AMPLIFIER The µPC4091 operational amplifier offers high input impedance, low offset voltage, high slew rate, and stable AC operating characteristics. NEC's unique high-speed PNP transistor (fT = 300 MHz) in the output stage solves the oscillation problem of current sinking with a large capacitive load. Zener-zap resistor trimming...
