Operation on ±5V or +10V supplies is also supported. The input range extends below the negative supply and to within 1.7V of the positive supply. Using complementary common-emitter outputs provides an output swing to within 25mV of either supply while driving 150Ω. High output drive current (±80mA) and low differential gain and phase errors also make them ideal for singlesupply consumer video products. Low distortion operation is ensured by the high gain bandwidth product (110MHz) and slew rate (550V/μs), making the OPA830 an ideal input buffer stage to 3V and 5V CMOS ADCs. Unlike other lowpower...
