AD813
High Performance Video Line Driver
At a gain of +2, the AD813 makes an excellent driver for a back
terminated 75
errors and wide 0.1 dB bandwidth can be realized over a wide
range of power supply voltage. Excellent gain and group delay
matching are also attainable over the full operating supply volt-
age range.

Figures 50 and 51 show the worst case matching; the match
between amplifiers 2 and 3 is typically much better than this.
