... TDA7567PD 3.3 Output DC offset detection Any DC output offset exceeding ±2 V are signalled out. This inconvenient might occur as a consequence of initially defective or aged and worn-out input capacitors feeding a DC component to the inputs, so putting the speakers at risk of overheating. This diagnostic has to be performed with low-level output AC signal (or V The test is run with selectable time duration by microprocessor (from a " ...

... TDA7567PD 6 Fast muting The muting time can be shortened to less than 1 setting (IB2 This option can be useful in transient battery situations (i.e. during car engine cranking) to quickly turnoff the amplifier for avoiding any audible effects caused by noise/transients being injected by preamp stages. The bit must be set back to “0” shortly after the mute transition. ...
