OPA890 Low-Power, Wideband, Voltage Feedback Operational Amplifier with Disable
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
