BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC4092
J-FET INPUT LOW-OFFSET DUAL OPERATIONAL AMPLIFIER
The µPC4092 dual 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 in the input stage
produces excellent offset voltage and temperature drift characteristics.
FEATURES
• Stable operation with 10000 pF capacitive load
• Low input 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: 15 V/µs (TYP.)
