In this post we learn the datasheet of the IC TDA7560 which is a cutting-edge BCD (Bipolar / CMOS / DMOS) technology class AB 4 x 45 quad Audio Power Amplifier in Flexiwatt 25 package made for super high power car radio.
The thoroughly interdependent P-Channel/N-Channel output composition makes it possible for a rail to rail output voltage swing which, linked with high output current and minimized saturation cuts sets latest power references in the car-radio niche, with optimal distortion activities.
DC OFFSET DETECTOR
The TDA7560 integrates a DC offset detector to evade that an anomalous DC offset on the inputs of the amplifier could possibly be multiplied by the gain and contribute to an unfavorable significant offset on the outputs that might cause speakers problems for overheating.
The feature is allowed by the MUTE pin and fits well with the amplifier umuted and without signal on the inputs. The DC offset diagnosis is signaled out on the HSD pin.
STAND-BY AND MUTING STAND-BY and MUTING facilities are both CMOS-COMPATIBLE. In shortage of correct CMOS ports or microprocessors, an immediate connection to Vs of these two pins is admissible still a 470 kOhm similar resistance ought to give between the power and the muting together with stand-by pins.
