DESCRIPTION
The OPA634 and OPA635 are low-power, voltagefeedback, high-speed amplifiers designed to operate on +3V or +5V single-supply voltages. 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. The high output drive current, low differential gain and phase errors make them ideal for single-supply composite video line driving. Low-distortion operation is ensured by the high gain bandwidth product (140MHz) and slew rate (250V/µs). This makes the OPA634 and OPA635 ideal input buffer stages 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 input voltage noise supports wide dynamic range operation. Multiplexing or system power reduction can be achieved using the high-speed disable line with the OPA635. Power dissipation can be reduced to zero by taking the disable line HIGH. The OPA634 and OPA635 are available in an industry standard SO-8 package. The OPA634 is also available in an ultra-small SOT23-5 package, while the OPA635 is available in the SOT23-6. Where lower supply current and speed are required, consider the OPA631 and OPA632. RELATED PRODUCTS
