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  
(G = +2V/V)  
•
•
•
•
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.
