The THS3001 may also be employed as a good video distribution amplifier. One characteristic of distribution
amplifiers is the fact that the differential phase (DP) and the differential gain (DG) are compromised as the
number of lines increases and the closed-loop gain increases (see Figures 22 to 25 for more information). Be
sure to use termination resistors throughout the distribution system to minimize reflections and capacitive
loading.
