Another good use for the THS6002 driver amplifiers are as very good video distribution amplifiers. 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. Be sure to use
termination resistors throughout the distribution system to minimize reflections and capacitive loading.

evaluation board
An evaluation board is available for the THS6002 (literature number SLOP117). This board has been configured
for proper thermal management of the THS6002. The circuitry has been designed for a typical ADSL application
as shown previously in this document. For more detailed information, refer to the THS6002EVM User’s Manual
(literature number SLOU018). To order the evaluation board contact your local TI sales office or distributor.
