OPA2889IDGSR

高速运算放大器 Dual Lo Pwr Vltg Op Amp

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.
