OPA2691的产品详情:

The OPA2691 sets a new level of performance for broadband dual current-feedback op amps. Operating on a very low 5.1mA/ch supply current, the OPA2691 offers a slew rate and output power normally associated with a much higher supply current. A new output stage architecture delivers a high output current with minimal voltage headroom and crossover distortion. This gives exceptional single-supply operation. Using a single +5V supply, the OPA2691 can deliver a 1V to 4V output swing with over 150mA drive current and 190MHz bandwidth. This combination of features makes the OPA2691 an ideal RGB line driver or single-supply Analog-to-Digital Converter (ADC) input driver.

The OPA2691’s low 5.1mA/ch supply current is precisely trimmed at 25°C. This trim, along with low drift over temperature, ensures lower maximum supply current than competing products. System power may be further reduced by using the optional disable control pin (SO-14 only). Leaving this disable pin open, or holding it HIGH, gives normal operation. If pulled LOW, the OPA2691 supply current drops to less than 150 µA/ch while the output goes into a high impedance state. This feature may be used for power savings.
