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 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.
