In most video applications the signal levels are significantly
lower than the 20V peak-to-peak capability of the BUF-03.
This suggests operating the SUF-03 at reduced power
suppJiea; for example. at f:6V supplies :t2V signals can be
handled. The obvious advantage of reduced supplies is the
accompanying decrease in power pissipation: from a typical
540mW (=30V x 18mA)to 195mW(= 12VX 16.2mA)atf:6V. At
lower supply voltages heat sinking Is no longer necessary.
son
However, as shown on the slew rate vs supply voltage curve,
slew rate does degrade at lower supplies. This occurs
because of higher internal node capacitances at lower
voltages and because of the slightlydecreased operating
current.
