3 DC Offset Detector
The TDA7560 The TDA7560 integrates a DC offset detector to avoid that an anomalous DC offset on the
inputs of the amplifier may be multiplied by the gain and result in a dangerous large offset on the outputs
which may lead to speakers damage for overheating.
The feature is enabled by the MUTE pin and works with the amplifier umuted and with no signal on the
inputs. The DC offset detection is signaled out on the HSD pin.
