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.
