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-

IN0

lowing:

| | For VOUT > 0V: VCC - VOUT ILOAD

75Ω

OR

| | For VOUT < 0V: VEE - VOUT ILOAD.

These devices can drive 100Ω loads connected to

each of the outputs over the entire rated output swing

and temperature range. When driving 50Ω loads with

each of the four outputs simultaneously, the output

swing must be limited to ±1.25V at TA = +70°C. While

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.
