High-Speed Buffer Amps Serve Video Line Driver Apps

A high bandwidth of 240 MHz and high slew rate of 2100V/µs at a gain of +2 suit the OPA682 series of high-speed video buffer amplifiers for use in driving matched coax lines in video signal distribution applications. The fixed gain video line driver delivers a wideband but precise gain of +1 to matched loads where signals must be transmitted between various pieces of video processing equipment. Operating on a very low, 6 mA/channel supply current, the device delivers high output current with minimal headroom and crossover distortion for what’s reported as excellent single supply operation. Using a single 5V supply, the series can deliver a 1V to 4V output swing with over 100 mA drive current and 200 MHz bandwidth. The dual OPA2682 can be used as a wideband differential receiver providing buffered differential I/O.
