The OPA693 provides an easy to use, broadband, fixed gain buffer amplifier. Depending on the external connections, the internal resistor network may be used to provide either a fixed gain of +2 video buffer or a gain of ±1 voltage buffer. Operating on a low 13mA supply current, the OPA693 offers a slew rate (2500V/µs) and bandwidth (> 700MHz) normally associated with a much higher supply current. A new output stage architecture delivers high output current with a minimal headroom and crossover distortion. This gives exceptional single-supply operation. Using a single +5V supply, the OPA693 can deliver a 2.5V_PP swing with over 90mA drive current and 500MHz bandwidth at a gain of +2. This combination of features makes the OPA693 an ideal RGB line driver or single-supply undersampling Analog-to-Digital Converter (ADC) input driver.

The OPA693’s low 13mA supply current is precisely trimmed at 25°C. This trim, along with low drift over temperature, ensures lower maximum supply current than competing products that report only a room temperature nominal supply current. System power may be further reduced by using the optional disable control pin. Leaving this disable pin open, or holding it HIGH, gives normal operation. This optional disable allows the OPA693 to fit into existing video buffer layouts where the disable pin is unconnected to get improved performance with no board changes. If pulled LOW, the OPA693 supply current drops to less than 170µA while the output goes into a high impedance state. This feature may be used for power savings.

The low gain stable current-feedback architecture used in the OPA693 is particularly suitable for high full-power bandwidth cable driving requirements. Where the additional flexibility of an op amp is required, consider the OPA695 ultra-wideband current feedback op amp. Where a unity gain stable voltage feedback op amp with very high slew rate is required, consider the OPA690.
