... K/W can be calculated. th(j-a) The R of the TDA8922 in free air is 35 K/W; the R th(j-a) of the TDA8922 is 1.3 K/W, thus a heatsink of 20.1 K/W is required for this example. In actual applications, other factors such as the average power dissipation with music source (as opposed to a continuous sine wave) will determine the size of the heatsink required ...
