DESCRIPTION
The TDA7562 is a new BCD technology QUAD
BRIDGE type of car radio amplifier in Flexiwatt27
BLOCK DIAGRAM
MULTIPOWER BCD TECHNOLOGY
MOSFET OUTPUT POWER STAGE
FLEXIWATT27
package specially intended for car radio applica-
tions. Thanks to the DMOS output stage the
TDA7562 has a very low distortion allowing a
clear powerful sound.
This device is equipped with a full diagnostics array
that commtgiicates the status of each speaker
through the I C bus.
The possibility to control the configuration grid the
behaviour of the device by means of the I C bus
makes TDA7562 a very flexible machine.
