DESCRIPTION

The μPC811 operational amplifier offers high input

impedance, low offset voltage, high slew rate, and

stable AC operating characteristics. NEC's unique

high-speed PNP transistor (fr-300 MHz) in the output

stage solves the oscillation problem of current sink-

ing with a large capacitive load. Zener-zap resistor

trimming in the input stage produces excellent offset

voltage and temperature drift characteristics.
