SBOS373–JUNE 2007
Dual, Low-Power, Wideband, Voltage-Feedback
OPERATIONAL AMPLIFIER with Disable
FEATURES
DESCRIPTION
•
FLEXIBLE SUPPLY RANGE:
+2.6V to +12V Single Supply
±1.3V to ±6V Dual Supplies
The OPA2889 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 give exceptional full-power bandwidth.
Using a dual ±5V supply, the OPA2889 can deliver a
±4V output swing with over 40mA drive current and
60MHz bandwidth. This combination of features
makes the OPA2889 an ideal RGB line driver or
single-supply analog-to-digital converter (ADC) input
driver or low power twisted pair line receiver.

UNITY-GAIN STABLE
WIDEBAND ±5V OPERATION: 60MHz

OUTPUT VOLTAGE SWING: ±4V
HIGH SLEW RATE: 250V/μs
LOW QUIESCENT CURRENT: 460μA/ch
LOW DISABLE CURRENT: 18μA/ch
APPLICATIONS
The low 460μA/ch supply current of the OPA2889 is
precisely trimmed at +25°C. System power may be
reduced further using the optional disable control pin.
Leaving this disable pin open, or holding it HIGH,
operates the OPA2889 normally. If pulled LOW, the
OPA2889 supply current drops to less than 20μA/ch
while the output goes into a high-impedance state.
