ad8055/AD8056 ? rev. f applications four-line video driver the ad8055 is a useful low cost circuit for driving up to four video lines. for such an application, the amplifier is configured for a noninverting gain of 2 as shown in figure 3. the input video source is terminated in 75 ? and applied to the high impedance noninverting input. each output cable is connected to the op amp output via a 75 ? s eries back termination resistor for proper cable termination. the terminating resistors at the other ends of the lines will divide the output signal by two, which is compensated for by the gain-of-two of the op amp stage. for a single load, the differential gain error of this circuit was measured to be 0.01%, with a differential phase error of 0.02 degrees. the two load measurements were 0.02% and 0.03 degrees, respectively. for four loads, the differential gain error is 0.02%, while the differential phase increases to 0.1 de grees. 0.1 f 10 f 75 402 ad8055 75 +5v ?v 0.1 f 10 f 402 75 75 75 v in 75 75 75 75 v out1 v out2 v out3 v out4 6 7 2 3 4 figure 3. four-line video driver single-ended to differential line driver c reating differential signals from single-ended signals is required for driving balanced, twisted pair cables, differential input a/d converters, and other applications that require differential signals. this is sometimes accomplished by using an inverting and a non- inverting amplifier stage to create the complementary signals. the circuit shown in figure 4 shows how an AD8056 can be used to make a single-ended to differential converter that offers some advantages over the architecture mentioned above. each op amp is configured for unity gain by the feedback resistors from the outputs to the inverting inputs. in addition, each output drives the opposite op amp with a gain of ? by means of the crossed resistors. the result of this is that the outputs are complementary and there is high gain in the overall configuration. feedback techniques similar to a conventional op amp are used to control the gain of the circuit. from the noninverting input of amp 1 to the output of amp 2 is an inverting gain. between these points a feedback resistor can be used to close the loop. as in the case of a conventional op amp inverting gain stage, an input resistor is added to vary the gain. the gain of this circuit from the input to amp 1 output is r f /r i , while the gain to the output of amp 2 is ? f /r i . the circuit thus creates a balanced differential output signal from a single-ended input. the advantage of this circuit is that the gain can be changed by changing a single resistor and still maintain the balanced differential outputs. 75 r i 402 +5v r f 402 ?v AD8056 402 402 402 49.9 49.9 v in +v out 402 ?

, eno ugh to accommodate a 4 v p-p sine wave signal on both outputs simultaneously. but since each output of the ad8055 or AD8056 is capable of supplying as much as 110 ma into a short circuit, a continuous short circuit condition will exceed the maximum safe junction temperature. resistor selection the following table is provided as a guide to resistor selection f or maintaining gain flatness vs. frequency for various values of gain. ?
