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 it ideal for singlesupply consumer video products. Low distortion operation is ensured by the high gain bandwidth (68MHz) and slew rate (100V/µs), making the OPA2631 an ideal input buffer stage to 3V and 5V CMOS converters. Unlike other low power, singlesupply amplifiers, distortion performance improves as the signal swing is decreased. A low 6nV/√Hz input voltage noise supports wide dynamic range operation. The OPA2631 is available in an industry standard SO-8 package. Where a single channel, single-supply operational amplifier is required, consider the OPA631 and OPA632. Where higher full-power bandwidth and lower distortion are required, consider the OPA2634.
