TDA2003A application information doc id 018796 rev 4 13/19 figure 22. voltage gain bridge configuration figure 23. suggested lc network circuit 3.1.2 short-circuit (ac and dc conditions) the TDA2003A can withstand a permanent short-circuit on the output for a supply voltage up to 16 v. 3.1.3 polarity inversion high current (up to 5 a) can be handled by the device with no damage for a longer period than the blow-out time of a quick 1 a fuse (normally connected in series with the supply). this feature is added to avoid destruction if, during fitting to the car, a mistake on the connection of the supply is made. 3.1.4 open ground when the radio is in the on condition and the ground is accidentally opened, a standard audio amplifier will be dam aged. on the TDA2003A, protection diodes are included to avoid any damage. 3.1.5 inductive load a protection diode is provided between pin 4 and 5 (see the internal schematic diagram) to allow use of the TDA2003A with inductive load s. in particular, the TDA2003A can drive a coupling transformer for audio modulation. 3.1.6 dc voltage the maximum operating dc voltage on the TDA2003A is 18 v, however the device can withstand a dc voltage up to 28 v with no damage. this could occur during winter if two batteries were connected in series to crank the engine. obsolete product(s) - obsolete product(s) http://
application information TDA2003A 14/19 doc id 018796 rev 4 3.1.7 thermal shutdown the presence of a thermal limiting circuit offers the following advantages: 1. an overload on the output (even if it is permanent), or an excessive ambient temperature can be easily withstood. 2. the heatsink can have a smaller factor compared with that of a conventional circuit. there is no damage to the device in the case of excessive junction temperature: only p o (and therefore p tot ) and id are reduced. 3.2 practical considerations 3.2.1 printed circuit board the layout shown in figure 21 is recommended. if different layouts are used, the ground points of input 1 and input 2 must be well decoupled from the ground of the output through which a rather high current flows. 3.2.2 assembly recommendations no electrical insulation is required between the package and the heatsink. pin length should be as short as possible. the soldering temperature must not exceed 260 c for 12 seconds. figure 24. output power and drain current vs. case temperature (r l = 4 ) figure 25. output power and drain current vs. case temperature (r l = 2 ) obsolete product(s) - obsolete product(s) http://
