DESCRIPTION
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.
