UPC4091C中文资料瑞萨数据手册PDF规格书

The µPC4091 operational amplifier offers high input impedance, low offset voltage, high slew rate, and stable AC operating characteristics. NECs 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.
