Description for the OPA890
The OPA890 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. These capabilities provide exceptional full power bandwidth. Using a single +5V supply, the OPA890 can deliver a 1V to 4V output swing with over 35mA drive current and 220MHz bandwidth. This combination of features makes the OPA890 an ideal RGB line driver or single-supply analog-to-digital converter (ADC) input driver.
The low 1.1mA supply current of the OPA890 is precisely trimmed at +25°C. This trim, along with low temperature drift, ensures 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 OPA890 normally. If pulled LOW, the OPA890 supply current drops to less than 30µA while the output goes into a high-impedance state.
