Even supplied with 12V the peaks will exceed 25V in any case.ĭriving the TDA2003 at it's maximum performance you should plan for a good heat sink (e.g. It must be able to stand peaks up to 40V. Special care must be taken of the output electronic capacitor (pin4 to speaker). Sign in JLCPCB to get coupons and free assembly service. Assembly Tips No longer need to assemble boards yourself, JLCPCB helps you assemble the part TDA2003 for free. This is extremely important to avoid oscillations of the amplifier and resultant overheating.Īlso planning the circuit layout please follow the exact trace routing as given in the data sheet (page 6/10) to avoid any complications concerning oscillations.Īnd, of course (as already pointed out by Torben) for a stereo amplifier you must have two identical boards. TDA2003 JLCPCB Part C2683155 Package TO-220B-5 Description TO-220B-5L Audio Power OpAmps ROHS Datasheet Download Source JLCPCB. Your schematic omits an extra 100♟ electrolytic capacitor for supply bypass. Please refer to the ST TDA2003 datasheet. (1A is a bit low, but might suffice for room volume settings - repetitive peak current is 3.5A) Using 2X15V the rectified and smoothened DC must not exceed 18V. You might choose either 2X11V or 2X15V for the supply transformer.
