UPC4093 - NEC

UPC4093 J-FET INPUT LOW-OFFSET OPERATIONAL AMPLIFIER

DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC4093 J-FET INPUT LOW-OFFSET OPERATIONAL AMPLIFIER The µPC4093 operational amplifier is a high-speed version of the µPC4091. NEC's unique high-speed PNP transistor (fT = 300 MHz) in the output stage realizes a high slew rate of 25 V/µs under voltage-follower conditions without an oscillation problem. Zener-z.
