J-FET INPUT LOW-OFFSET DUAL OPERATIONAL AMPLIFIER

Dual operational amplifier µPC4094 is a high-speed version of the µPC4092. NECs 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-zap resistor trimming in the input stage produces excellent offset voltage and temperature drift characteristics.

With AC performance characteristics that are two times better than conventional bi-FET operation amplifiers, the µPC4094 is ideal for fast integrators, active filters, and other high-speed circuit applications.
