• T
• θ
The maximum power dissipation actually produced by an IC
is the total quiescent supply current times the total power
supply voltage, plus the power in the IC due to the load, or:
Where:
• V
• I
• V
• R
• n = 1 to 16 channels
The required θ
Table 8 shows θ
Wakefield heatsink and without heatsink and various airflow.
At the thermal resistance equation shows, the required
thermal resistance depends on the maximum ambient
temperature.
