OPA2890IDGSR General Description

The OPA2890 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 give exceptional single-supply operation. Using a single +5V supply, the OPA2890 can deliver a 0.9V to 4.1V output swing with over 30mA drive current and 210MHz bandwidth. This combination of features makes the OPA2890 an ideal RGB line driver or single-supply analog-to-digital converter (ADC) input driver.

The low 1.1mA/ch supply current of the OPA2890 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 (MSOP-10 package only). Leaving this disable pin open, or holding it high, operates the OPA2890 normally. If pulled low, the OPA2890 supply current drops to less than 30µA/ch while the output goes into a high-impedance state.
