he OPA3692 provides an easy–to–use, broadband fixed gain, triple 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 5.1mA/ch supply current, the OPA3692 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 minimal headroom and crossover distortion. This gives exceptional single–supply operation. Using a single +5V supply, the OPA3692 can deliver a 1V to 4V output swing with over 120mA drive current and > 200MHz bandwidth. This combination of features makes the OPA3692 an ideal RGB line driver or single–supply, triple Analog–to– Digital Converter (ADC) input driver.

The low 5.1mA/ch supply current of the OPA3692 is precisely trimmed at +25°C. This trim, along with low drift over temperature, ensures lower maximum supply current than competing products that report only a room temperature nominal supply current. System power can 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 OPA3692 supply current drops to less than 150μA/ch while the output goes into a high–impedance state. This feature may be used for power savings.
