The TDA2005 has a circuit which enables it to withstand voltage pulse train, on Pin 9, of the
type shown in
must be inserted between the supply and pin 9, in order to assure that the pulses at pin 9
will be held within the limits shown.
A suggested LC network is shown in
amplitude up to 120 V and width of 2 ms can be applied at point A. This type of protection is
ON when the supply voltage (pulse or DC) exceeds 18 V. For this reason the maximum
operating supply voltage is 18 V.
