DESCRIPTION
The TDA7560 is a breakthrough BCD (Bipolar /
CMOS / DMOS) technology class AB Audio
Power Amplifier in Flexiwatt 25 package designed
for high power car radio
The fully complementary P-Channel/N-Channel
output structure allows a rail to rail output voltage
swing which, combined with high output current
and minimised saturation losses sets new power
references in the car-radio field, with unparalleled distortion performances.

APPLICATION HINTS (ref. to the circuit of fig. 1)
SVR
Besides its contribution to the ripple rejection, the
SVR capacitor governs the turn ON/OFF time sequence and, consequently, plays an essential role
in the pop optimization during ON/OFF transients.To conveniently serve both needs, ITS
MINIMUM RECOMMENDED VALUE IS 10µF.

be employed to drive muting and stand-by pins in
absence of true CMOS ports or microprocessors.
R-C cells have always to be used in order to
smooth down the transitions for preventing any
audible transient noises.
About the stand-by, the time constant to be assigned in order to obtain a virtually pop-free transition has to be slower than 2.5V/ms.

INPUT STAGE
The TDA7560’s inputs are ground-compatible and
can stand very high input signals (± 8Vpk) without
any performances degradation.
If the standard value for the input capacitors
(0.1µF) is adopted, the low frequency cut-off will
amount to 16 Hz.

HEATSINK DEFINITION
Under normal usage (4 Ohm speakers) the
heatsink’s thermal requirements have to be deduced from fig. 15, which reports the simulated
power dissipation when real music/speech programmes are played out. Noise with gaussiandistributed amplitude was employed for this simulation. Based on that, frequent clipping occurence
(worst-case) will cause Pdiss = 26W. Assuming
Tamb = 70°C and TCHIP = 150°C as boundary
conditions, the heatsink’s thermal resistance
should be approximately 2°C/W. This would avoid
any thermal shutdown occurence even after longterm and full-volume operation.

STAND-BY AND MUTING
STAND-BY and MUTING facilities are both
CMOS-COMPATIBLE. If unused, a straight connection to Vs of their respective pins would be admissible. Conventional low-power transistors can
