DESCRIPTION
The OPA2682 provides an easy to use, broadband fixed gain, dual buffer amplifier. Depending on the external connections, the internal resistor network may be used to provide either a fixed gain of +2 video buffer or a gain of +1 or 1 voltage buffer. Operating on a very low 6mA/ch supply current, the OPA2682 offers a slew rate and output power normally associated with a much higher supply current. A new output stage architecture delivers high output current with a minimal headroom and crossover distortion. This gives exceptional single supply operation. Using a single +5V supply, the OPA2682 can deliver a 1V to 4V output swing with over 100mA drive current and 200MHz bandwidth. This combination of features makes the OPA2682 an ideal RGB line driver or single-supply ADC input driver.
The OPA2682's low 6mA/ch supply current is precisely trimmed at 25°C. This trim, along with low drift over temperature, guarantees lower maximum supply current than competing products that report only a room temperature nominal supply current. 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 OPA2682 supply current drops to less than 320µA/ch while the output goes into a high impedance state. This feature may be used for either power savings or for video MUX applications.
