Heatsink requirements
As with most amplifiers, the power dissipated within the device depends primarily on the
supply voltage, the load impedance and the output modulation level.
The maximum estimated power dissipation for the TDA7492 is around 7 W. At 25 °C
ambient a heatsink having Rth =15 °C/W is sufficient for sine-wave testing at maximum
power. A musical program, however, dissipates about 40% less power than this and a
heatsink with Rth = 25 °C/W is, thus, recommended. Even at the maximum recommended
ambient temperature for consumer applications of 50 °C there is still a clear safety margin
before the maximum junction temperature (150 °C) is reached.
