The OPA2634 is a dual, low power, voltage-feedback, high-speed operational amplifier designed to operate on +3V or +5V single-supply voltage. Operation on 5V or +10V supplies is also supported. The input range extends below ground and to within 1.2V of the positive supply. Using complementary common-emitter outputs provides an output swing to within 30mV of ground and 140mV of positive supply. Low distortion operation is ensured by the high gain bandwidth (140MHz) and slew rate (250V/s). This makes the OPA2634 an ideal differential input buffer stage to 3V and 5V CMOS converters. Unlike other low power, single-supply operational amplifiers, distortion performance improves as the signal swing is decreased. A low 5.6nV/Hz input voltage noise supports wide dynamic range operation. The OPA2634 is available in an industry-standard dual pinout SO-8 package. Where a single channel, singlesupply operational amplifier is required, consider the OPA634 and OPA635. Where lower supply current and speed are required, consider the OPA2631.
