1 / 20 page  1/20 TDA7564 September 2003 s DMOS POWER OUTPUT s NON-SWITCHING HI-EFFICIENCY s HIGH OUTPUT POWER CAPABILITY 4x28W/4 Ω @ 14.4V, 1KHZ, 10% THD, 4x40W EIAJ s MAX. OUTPUT POWER 4x72W/2 Ω s FULL I2C BUS DRIVING: –ST-BY – INDEPENDENT FRONT/REAR SOFT PLAY/ MUTE – SELECTABLE GAIN 26dB - 12dB (FOR LOW NOISE LINE OUTPUT FUNCTION) – HIGH EFFICIENCY ENABLE/DISABLE –I2C BUS DIGITAL DIAGNOSTICS s FULL FAULT PROTECTION s DC OFFSET DETECTION s FOUR INDEPENDENT SHORT CIRCUIT PROTECTION s CLIPPING DETECTOR (2% - 10%) PROTECTION DESCRIPTION The TDA7564 is a new BCD technology QUAD BRIDGE type of car radio amplifier in Flexiwatt25 package specially intended for car radio applica- tions. Thanks to the DMOS output stage the TDA7564 has a very low distortion allowing a clear powerful sound. Among the features, its superior efficiency performance coming from the internal exclusive structure, makes it the most suitable de- vice to simplify the thermal management in high power sets.The dissipated output power under av- erage listening condition is in fact reduced up to 50% when compared to the level provided by con- ventional class AB solutions.This device is equipped with a full diagnostics array that commu- nicates the status of each speaker through the I2C bus.The possibility to control the configuration and behaviour of the device by means of the I2C bus makes TDA7564 a very flexible machine.
