UPC4093

DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC4093 J-FET INPUT LOW-OFFSET OPERATIONAL AMPLIFIER The µPC4093 operational amplifier is a high-speed version of the µPC4091. 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 µPC4093 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 null capability ±2.5 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.)
