BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC4094
J-FET INPUT LOW-OFFSET DUAL OPERATIONAL AMPLIFIER
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.
FEATURES
• 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.)
