DESCRIPTION

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.

The low 460mA/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 20mA/ch

while the output goes into a high-impedance state.
