DESCRIPTION
The OPA2680 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 OPA2680 can deliver a 1V to 4V output swing with over 100mA drive current and 150MHz bandwidth. This combination of features makes the OPA2680 an ideal RGB line driver or single supply ADC input driver.
The OPA2680's low 6.4mA/ch. supply current is precisely trimmed at 25°C. 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 (SO-14 package only). Leaving this disable pin open, or holding it high, will operate the OPA2680N normally. If pulled low, the OPA2680N supply current drops to less than 600µA while the output goes into a high impedance state. OPA2680 RELATED PRODUCTS
