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擄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

30碌A(chǔ) while the output goes into a high-impedance

state.
