Overview

Dual operational amplifier µPC4094 is a high-speed version of the µPC4092. 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-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.

  • Stable operation with 220 pF capacitive load
  • Low input offset voltage and offset voltage ±3 mV (MAX.) ±7 µV/°C (TYP.) temperature drift
  • Very low input bias and offset currents
  • Low noise: en = 19 nV/ √Hz (TYP.)
  • Output short circuit protection
  • High input impedance ... J-FET Input Stage
  • Internal frequency compensation
  • High slew rate: 25 V/ µs (TYP.)
