The TDA8565Q contains four identical amplifiers which
can be used for single-ended applications. The gain of
each amplifier is fixed at 40 dB. Special features of the
device are as follows.

• Low standby current (<100 µA)
• Low switching current (low cost supply switch)
• Mute facility.
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 pins 1, 3, 15 and 17).
This can be achieved by:
• Microcontroller control
• External timing circuit (see Fig.3).
The circuit in Fig.3 slowly ramps up the voltage at the
mode select switch pin when switching on and results in
fast muting when switching off.
In the event of fast switching at mode select pin it is
advised to increase the
1
⁄2VP decoupling capacitor (pin 4)
to 150 µF to avoid switch plops.

Diagnostic output (pin 16)
D
YNAMIC DISTORTION DETECTOR (DDD)
At the onset of clipping of one or more output stages, the
dynamic distortion detector becomes active and pin 16
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 16 is independent of the number of channels that are
clipping (see Fig.4).
HORT-CIRCUIT PROTECTION
S
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 16 is continuously LOW.
When a short-circuit across the load of one or more
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).
During this short-circuit condition, pin 16 is LOW for 20 ms
and HIGH for 50 µs (see Fig.5).

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
our
“IC Package Databook”
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).
TDA8565Q
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.
