For external buffering of the ADV7177/ADV7178 DAC out-
puts, the configuration in Figure 67 is recommended. This
configuration shows the DAC outputs running at half (18 mA)
their full current (34.7 mA) capability. This will allow the
ADV7177/ADV7178 to dissipate less power, the analog current is
reduced by 50% with a R
SET
of 300
and a R
LOAD
of 75
. This
mode is recommended for 3.3 volt operation as optimum perfor-
mance is obtained from the DAC outputs at 18 mA with a V
AA
of
3.3 volts. This buffer also adds extra isolation on the video out-
