Once power dissipation greater than maximum limit (PD,MAX), either supply voltage (VDD) must decreased, load impedance (RL) must increased ambient temperature should reduced. Thermal Considerations thermal must connected ground. package with thermal APA0710/1 requires special attention thermal design. thermal design issues properly addressed, APA0710/1 will into thermal shutdown when driving load. thermal bottom APA0710/1 should soldered down copper circuit board. Heat conducted away from thermal through copper plane ambient. copper plane surface circuit board, vias smaller diameter should used thermally couple thermal bottom plane. good thermal conduction, vias must plated through solder filled. copper plane used conduct heat away from thermal should large practical. ambient temperature higher than 25°C, larger copper plane forced-air cooling will required keep APA0710/1 junction temperature below thermal shutdown temperature (170°C). higher ambient temperature, higher airflow rate and/or larger copper area will required keep thermal shutdown.

Since APA0710/1 mono channel power amplifier, maximum internal power dissipation equal both equations depending mode operation. Even with this substantial increase power dissipation, APA0710/1 does require extra heatsink. power dissipation from equation12, assuming 5V-power supply load, must greater than power dissipation that results from equation13 TJ,MAX (13) PD,MAX= MSOP-8-P package with SOP-8 without
