The OPA690 device represents a major step forward in unity-gain stable, voltage-feedback op amps. A new internal architecture provides slew rate and full-power bandwidth previously found only in wideband, current-feedback op amps. A new output stage architecture delivers high currents with a minimal headroom requirement. These combine to give exceptional single-supply operation. Using a single 5-V supply, the OPA690 can deliver a 1-V to 4-V output swing with over 150 mA drive current and 150 MHz bandwidth. This combination of features makes the OPA690 an ideal RGB line driver or single-supply Analog-to-Digital Converter (ADC) input driver.

The low 5.5-mA supply current of the OPA690 is precisely trimmed at 25°C. This trim, along with low temperature drift, gives lower maximum supply current than competing products. System power may be reduced further using the optional disable control pin. Leaving this disable pin open, or holding it HIGH, operates the OPA690 normally. If pulled LOW, the OPA690 supply current drops to less than 100 µA while the output goes to a high-impedance state. This feature may be used for power savings.
