Leave a Comment
Features

  • DMOS power output
  • High output power capability 4 x 25 W/4  @ 
  • 14.4 V, 1 kHz, 10 % THD, 4 x 40 W max. power
  • Max. output power 4 x 60 W/2 
  • Full I2C bus driving:
  • Standby
  • Independent front/rear soft play/mute
  • Selectable gain 26 dB - 12 dB
  • I2C bus digital diagnostics
  • Full fault protection
  • DC offset detection
  • Four independent short circuit protection
  • Clipping detector pin with selectable threshold (1%, 10%)
  • ESD protection

Description

The TDA7566 is a new BCD technology quad bridge type of car radio amplifier in Flexiwatt25  package specially intended for car radio applications. Thanks to the DMOS output stage the TDA7566 has a very low distortion allowing a clear powerful sound. This device is equipped with a full diagnostics array that communicates the status of each speaker through the I2C bus.The possibility to control the configuration and behavior of the device by means of the I2C bus makes TDA7566 a very flexible product.
