OPA680

The OPA680 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  device can deliver a 1V to 4V output swing with over 100mA drive current and 150MHz bandwidth. This combination of features makes the OPA680 an ideal RGB line driver or single supply ADC input driver.

The OPA680's low 6.4mA supply current is precisely trimmed at 25. This trim, along with low temperature drift, guarantees 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 OPA680 normally.

If pulled low, the OPA680 supply current drops to less than 300mA while the output goes to a high impedance state. This feature may be used for either power savings or to implement video MUX applications.
