FEATURES
•
FLEXIBLE SUPPLY RANGE:
+3V to +12V Single Supply
±1.5V
to
±6V
Dual Supplies
UNITY-GAIN STABLE
WIDEBAND +5V OPERATION: 115MHz
(G = +2V/V)
OUTPUT VOLTAGE SWING:
±4V
HIGH SLEW RATE: 500V/µs
LOW QUIESCENT CURRENT: 1.1mA
LOW DISABLE CURRENT: 30µA
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.

SBOS369 – MAY 2007
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
