Operational Amplifiers - Op Amps High-Speed Precision Difet
The OPA681 sets a new level of performance for broadband current feedback op amps. Operating on a very low 6mA supply current, the device 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 OPA681 can deliver a 1V to 4V output swing with over 100mA drive current and 150MHz bandwidth. This combination of features makes the OPA681 an ideal RGB line driver or single-supply ADC input driver.
The OPA681's low 6mA supply current is precisely trimmed at 25. This trim, along with low drift over temperature,guarantees lower guaranteed maximum supply current than competing products. System power may be further reduced by using the optional disable control pin. Leaving this disable pin open, or holding it high, gives normal operation. If pulled low, the OPA681 supply current drops to less than 320mA while the output goes into a high impedance state. This feature may be used for either power savings or for video MUX applications.
