4 x 50W quad power amplifier TDA7564B

Features:
■ Multipower BCD technology ■ MOSFET output power stage ■ DMOS power output ■ New high efficiency (class SB) ■ High output power capability 4x28 W/4  @  14.4 V, 1 kHz, 10 % THD, 4x50 W max, power  ■ Max. output power 4x72 W/2  ■ Full I2C bus driving: – Standby – Independent front/rear soft play/mute – Selectable gain (for low noise line output  function) – High efficiency enable/disable – I2C bus digital diagnostics (including AC  and DC load detection) ■ Full fault protection ■ DC offset detection ■ Four independent short circuit protection ■ Clipping detector (2 %/10 %) ■ Linear thermal shutdown with multiple thermal  warning ■ ESD protection
Description:
The TDA7564B is a new BCD technology quad bridge type of car radio amplifier in Flexiwatt25 / PowerSO36 package specially intended for car radio applications. Thanks to the DMOS output stage the TDA7564B has a very low distortion allowing a clear powerful sound. Among the features, its superior efficiency performance coming from the internal e…
