DESCRIPTION
The OPA631 and OPA632 are low-power, high-speed, voltage-feedback amplifiers designed to operate on a single +3V or +5V supply. 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 product (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 on the OPA632. Power dissipation can be reduced to zero by taking the disable line HIGH. The OPA631 and OPA632 are available in an industrystandard SO-8 package. The OPA631 is also available in an ultra-small SOT23-5 package, while the OPA632 is available in the SOT23-6. Where higher full-power bandwidth and lower distortion are required in a singlesupply operational amplifier, consider the OPA634 and OPA635. RELATED PRODUCTS
