TDA7563A 4 x 50 W power amplifier with high efficiency 2 and built-in I C diagnostic Datasheet - production data Full fault protection DC offset detection Four independent short circuit protection Clipping detector pin with selectable threshold Flexiwatt27 (Horiz.) Flexiwatt27 (SMD) (2 %/10 %) Standby/mute pin Linear thermal shutdown with multiple thermal warning PowerSO36 (Slug up) Flexiwatt27 (Vert.) ESD protection Description Features The TDA7563A is a new BCD technology Quad Multipower BCD technology Bridge type of car radio amplifier in Flexiwatt27 & MOSFET output power stage PowerSO36 packages specially intended for car radio applications. DMOS power output Thanks to the DMOS output stage the TDA7563A New high efficiency (class SB) has a very low distortion allowing a clear powerful High output power capability 4 x 28 W / 4 sound. Among the features, its superior efficiency 14.4 V, 1 kHz, 10 % THD, 4 x 50 W max power performance coming from the internal exclusive Max. output power 4 x 72 W / 2 structure, makes it the most suitable device to 2 simplify the thermal management in high power sets. Full I C bus driving: Standby The dissipated output power under average Independent front/rear soft play/mute listening condition is in fact reduced up to 50% when compared to the level provided by Selectable gain 26 dB /12 dB (for low noise conventional class AB solutions. line output function) High efficiency enable/disable This device is equipped with a full diagnostics 2 I C bus digital diagnostics (including DC array that communicates the status of each 2 and AC load detection) speaker through the I C bus.
