... The device provides a high output current capability (up to 3.5A) very low harmonic and cross-over distortion. Completely safe operation is guaranteed due to protection against DC and AC short circuit between all pins and ground, thermal over-range, load dump voltage surge up to 40V and fortuitous open ground. ...

... A suggested LC network is shown in fig. 19. With this network, a train of pulses with amplitude up to 120V and width can be applied at point A. This type of protection is ON when the supply voltage (pulsed or DC) exceeds 18V. For this reason the maximum operating supply voltage is 18V. ...

... Figure 18. Short-circuit (AC and DC conditions) The TDA 2003 can withstand a permanent short- circuit on the output for a supply voltage up to 16V. Polarity inversion High current (up to 5A) can be handled by the device with no damage for a longer period than the blow-out time of a quick 1A fuse (normally con- nected in series with the supply) ...

... PRATICAL CONSIDERATION Printed circuit board The layout shown in fig 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. Assembly suggestion No electrical insulation is required between the ...
