Page 1
... The AD8129 is a low noise, high gain (10 or greater) version intended for applications over very long cables, where signal attenuation is significant. The AD8130 is stable at a gain of 1 and can be used for applications where lower gains are required. Both have user-adjustable gain to help compensate for losses in the transmission line ...

... A few simple circuits can illustrate how the active feedback architecture of the AD8129/AD8130 operates. OP AMP CONFIGURATION If only one of the input stages of the AD8129/AD8130 is used, it functions very much like a conventional op amp (see Figure 131). Classical inverting and noninverting op amps circuits can be created, and the basic governing equations are the same as for a conventional op amp ...
Page 33
... APPLICATIONS BASIC GAIN CIRCUITS The gain of the AD8129/AD8130 can be set with a pair of feedback resistors. The basic configuration is shown in Figure 132. The gain equation is the same as that of a conventional op amp For unity-gain applications using the AD8130 can be set to 0 (short circuit), and R ...

... F bandwidth response decreases accordingly. By this technique, four signals can be summed by applying them to two AD8130s and then summing the two outputs by a third AD8130. CABLE-TAP AMPLIFIER It is often desirable to have a video signal drive several pieces of equipment. However, the cable should only be terminated once at its endpoint ...

... VIDEO IN –V 75 Ω Figure 143. The AD8130 Can Tap the Video Signal at Any Point Along the Cable Without Loading the Signal. The center conductor connects to the positive differential input of the AD8130. The amplitude of the video signal at this point is unity, because it is between the two termination resistors. The AD8130 provides a high impedance to this signal so that the signal is not disturbed ...
Page 37
... Another is to use a lower supply voltage unless absolutely necessary. Finally, do not use the AD8129/AD8130 when it is operating on high supply voltages to directly drive a heavy load best to use a second op amp after the output stage. Some of the gain can be shifted to this stage so that the signal swing at the output of the AD8129/AD8130 is not too large ...

... PCB design practice. The first requirement is for a good solid ground plane that covers as much of the board area around the AD8129/AD8130 as possible. The only exception to this is that the ground plane around the FB pin should be kept a few millimeters away, and the ground should be removed from the inner layers and the opposite side of the board under this pin ...
