DESCRIPTION
The OPA890 represents a major step forward in
unity-gain stable, voltage-feedback op amps. A new
internal
full-power bandwidth previously found only
wideband,
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
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
30 A while the output goes into a high-impedance
state.
