Another good use for the THS6012 amplifiers is 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 THS6012 (literature number SLOP132). This board has been configured
for proper thermal management of the THS6012. The circuitry has been designed for a typical ADSL application
as shown previously in this document. For more detailed information, refer to the THS6012EVM User's Manual
(literature number SLOU034). To order the evaluation board contact your local TI sales office or distributor.
