... For the average listening level a power dissipation can be used for a heatsink calculation. 8.3 Mode selection The TDA8946J has three functional modes, which can be selected by applying the proper DC voltage to pin MODE. See which depend on the supply voltage level. The MODE pin can be driven by a 3-state logic output stage: e ...

... A larger capacitor value on the SVR pin improves the ripple rejection behaviour at the lower frequencies. 8.5 Built-in protection circuits The TDA8946J contains two types of protection circuits, i.e. short-circuit and thermal shutdown. 8.5.1 Short-circuit protection Short-circuit to ground or supply line — This is detected by a so-called ‘missing current’ ...
