NOISE LINE OUTPUT FUNCTION)

– I C BUS DIGITAL DIAGNOSTICS

■ FULL FAULT PROTECTION

■ DC OFFSET DETECTION

FLEXIWATT25

■ FOUR INDEPENDENT SHORT CIRCUIT

PROTECTION

package specially intended for car radio applications.

Thanks to the DMOS output stage the TDA7561 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

■ CLIPPING DETECTOR

■ ESD PROTECTION

DESCRIPTION

through the I C bus.The possibility to control the con-

figuration and behaviour of the device by means of

the I C bus makes TDA7561 a very flexible machine.

The TDA7561 is a new BCD technology QUAD

BRIDGE type of car radio amplifier in Flexiwatt25
