Operation on ±5V or +10V supplies is also supported. The input range extends below ground and to within 1V of the positive supply. Using complementary common-emitter outputs provides an output swing to within 30mV of ground and 130mV of the positive supply. The high output drive current and low differential gain and phase errors also make them ideal for single-supply consumer video products. Low distortion operation is ensured by the high gain bandwidth (68MHz) and slew rate (100V/µs), making the OPA631 and OPA632 ideal input buffer stages to 3V and 5V CMOS converters. Unlike other low power, single-supply amplifiers, distortion performance improves as the signal swing is decreased. A low 6nV input voltage noise supports wide dynamic range operation. Channel multiplexing or system power reduction can be achieved using the high speed disable line. Power dissipation can be reduced to zero by taking the disa...
