The OPA690 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 +5V supply， the OPA690 can deliver a 1V

　　to 4V output swing with over 150mA drive current and

　　150MHz 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 5.5mA 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， will operate the OPA690 normally. If

　　pulled LOW， the OPA690 supply current drops to less than

　　100μA while the output goes to a high-impedance state.
