Abstract :
A high-speed, low-power voltage-feedback operational amplifier on a low-cost 40 volt complementary bipolar technology is described. The low-current version of this chip has a quiescent current of 2.5 mA at +/-15 V supply voltage, bandwidth of 110 MHz and slew rate of 2000 V/us. The medium-current version draws 6.5 mA of current at the same supply voltage while the bandwidth increases to 200 MHz and higher slewing characteristics. Both parts are operational from +/-3.75 V to +/-18 V supply range. Die size is 51 mils by 76 mils on a poly-emitter CB process
