Hello All,

 

Regarding the maximum power dissipation at Ta (85°C), could you let me know my understanding is correct or not?

Please see the attached picture, the yellow highlight area is maximum permissible power. Am I correct?

 

According to the ADuCM320 datasheet, it stated conditions below.

Maximum Power Dissipation: 1W

Thermal Performance Impedance junction to Ambient: 45°C/W

Maximum Operating Junction Temperature: +120°C

Operating Ambient Temperature Range: -40°C to +85°C

 

Thank you and best Regards,
