FUNCTIONAL DESCRIPTION

The TDA8560Q contains two identical amplifiers and can be used for bridge applications. The gain of each amplifier is fixed at 40 dB. Special features of the device are as follows.

Mode select switch (pin 11)

Standby: low supply current (<100 µA)
Mute: input signal suppressed
Operating: normal on condition.
Since this pin has a very low input current (<40 µA), a low cost supply switch can be applied.
To avoid switch-on plops, it is advised to keep the amplifier in the mute mode during 100 ms (charging of the input capacitors at pin 1 and pin 13).
This can be achieved by:
Microprocessor control
External timing circuit (see Fig.7).

Diagnostic output (pin 12)

YNAMIC DISTORTION DETECTOR (DDD)
D At the onset of clipping of one or more output stages, the
dynamic distortion detector becomes active and pin 12 goes low. This information can be used to drive a sound processor or DC volume control to attenuate the input signal and thus limit the distortion. The output level of pin 12 is independent of the number of channels that are clipping (see Fig.3).

SHORT-CIRCUIT PROTECTION When a short-circuit occurs at one or more outputs to
ground or to the supply voltage, the output stages are switched off until the short-circuit is removed and the device is switched on again, with a delay of approximately 20 ms, after removal of the short-circuit. During this short-circuit condition, pin 12 is continuously low.
When a short-circuit across the load of one or both channels occurs the output stages are switched off during approximately 20 ms. After that time it is checked during approximately 50 µs to see whether the short-circuit is still present. Due to this duty cycle of 50 µs/20 ms the average current consumption during this short-circuit condition is very low (approximately 40 mA).

TDA8560Q
During this short-circuit condition, pin 12 is low for 20 ms and high for 50 µs (see Fig.4).
The power dissipation in any short-circuit condition is very low.
TEMPERATURE DETECTION When the virtual junction temperature Tvj reaches 150 °C,
pin 12 will become continuously low.
PEN COLLECTOR OUTPUT
O Pin 12 is an open collector output, which allows pin 12 of
more devices being tied together.

Diagnostic output

Special care must be taken in the printed-circuit board layout to separate pin 12 from pin 1 and pin 13, to minimize the crosstalk between the diagnostic output and the inputs.
Mode select switch
To avoid switch-on plops, it is advised to keep the amplifier in the mute mode during >100 ms (charging of the input capacitors at pin 1 and pin 13).
The circuit in Fig.7 slowly ramps up the voltage at the mode select switch pin when switching on and results in fast muting when switching off.

SOLDERING Introduction
There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used.
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in
“IC Package Databook”
our
Soldering by dipping or by wave
The maximum permissible temperature of the solder is 260 °C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.
(order code 9398 652 90011).
TDA8560Q
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (T printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit.
Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 °C, contact may be up to 5 seconds.
