Increase of the Switch-on Time Smaller than Decrease of Gain Increase of Gain High Turn-on Pop. Higher Low Frequency Cut-off. Increase of Noise Degradation of SVR Danger of Oscillation Higher Low-frequency Cut-off (1) The closed loop gain must be higher than 26dB. BUILD-IN PROTECTION SYSTEMS THERMAL SHUT-DOWN The presence of a thermal limiting circuit offers the following advantages: 1) an averload on the output (even if it is perma nen t ), or an excessi ve ambient temperature can be easily withstood. 2) the heatsink can have a smaller factor of safety compared with that of a conventional circuit. There is no device damage in the case of excessive junction temperature : all that happens is that Po (and therefore Ptot) and Io are reduced. The maximum allowable power dissipation depends upon the size of the external heatsink (i.e. its thermal resistance); Figure 18 shows this dissipable power as a function of ambient temperature for different thermal resistance. Short circuit (AC Conditions). The TDA2009A can withstand an accidental short circuit from the output and ground made by a wrong connection during normal play operation. 9/12 TDA2009A MOUNTING INSTRUCTIONS The power dissipated in the circuit must be removed by adding an external heatsink. Thanks to the MULTIWATT package attaching Figure 18 : Maximum Allowable Power Dissipation versus Ambient Temperature Figure 20 : Output Power and Drain Current versus Case Temperature 10/12 the heatsink is very simple, a screw or a compression spring (clip) being sufficient. Between the heatsink and the package it is better to insert a layer of silicon grease, to optimize the thermal contact ; no electrical isolation is needed between the two Figure 19 : Output Power versus Case Temperature TDA2009A mm DIM.
