BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC4091
J-FET INPUT LOW-OFFSET OPERATIONAL AMPLIFIER
The µPC4091 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 and offset voltage null capability ±2.
5 mV (MAX.
) ±7 µV/°C (TYP.
) temperature drift • Very low inp...
