tda7560 application hints doc id 6886 rev 6 13/17 3 application hints (ref. to the circuit of figure 3 ) 3.1 svr besides its contribution to the ripple rejection, the svr capacitor governs the turn on/off time sequence and, consequently, plays an essential role in the pop optimization during on/off transients.to conveniently serve both needs, its minimum recommended value is 10 f . 3.2 input stage the tda7560's inputs are ground-compatible and can stand very high input signals (8 vpk) without any performances degradation. if the standard value for the input capacitors (0.1f) is adopted, the low frequency cut-off will amount to 16 hz. 3.3 standby and muting standby and muting facilities ar e both cmos-compatible. in abs ence of true cmos ports or microprocessors, a direct connection to vs of these two pins is admissible but a 470 kohm equivalent resistance should be present between the power supply and the muting and st-by pins. r-c cells have always to be used in order to smooth down the transitions for preventing any audible transient noises. about the standby, the time constant to be assigned in order to obtain a virtually pop-free transition has to be slower than 2.5 v/ms. 3.4 dc offset detector the tda7560 integrates a dc offset detector to avoid that an anomalous dc offset on the inputs of the amplifier may be multiplied by the gain and result in a dangerous large offset on the outputs which may lead to speakers damage for overheating. the feature is enabled by the mute pin (according to ta b l e 4 ) and works with the amplifier unmuted and with no signal on the inputs. the dc offset detection is signaled out on the hsd pin. to ensure the correct functionality of the offset detector it is necessary to connect a pulldown 10 k ? resistor between hsd and ground. 3.5 heatsink definition under normal usage (4 ohm speakers) the heatsink's thermal requirements have to be deduced from figure 17 , which reports the simulated power dissipation when real music/speech programmes are played out. noise with gaussian-distributed amplitude was employed for this simulation. based on that, frequent clipping occurrence (worst-case) will cause p diss = 26 w. assuming t amb = 70 c and t chip = 150 c as boundary conditions, the heatsink's thermal resistance should be app roximately 2 c/w. this would avoid any thermal shutdown occurrence even after long-term and full-volume operation
