Power Dissipation

The maximum output current of the MAX496/MAX497 is

limited by the packages maximum allowable power dis-

sipation. The maximum junction temperature should not

exceed +150°C. The power dissipation increases with

load, and this increase can be approximated by the fol-

lowing:

OR

These devices can drive 100

Ω loads connected to

each of the outputs over the entire rated output swing

and temperature range. When driving 50

Ω loads with

each of the four outputs simultaneously, the output

the output is short-circuit protected to 170mA, this does

not necessarily guarantee that, under all conditions, the

maximum junction temperature will not be exceeded.

Do not exceed the derating values given in the

absolute maximum ratings.
