FUNCTIONAL DESCRIPTION
17
The TDA8564Q contains four identical amplifiers which
can be used for single-ended or bridge applications. The
gain of each amplifier is fixed at 40 dB (46 dB in BTL).
Special features of the device are as follows.
MLC810

Mode select switch (pin 14)
• Low standby current (<100 µA)
• Low switching current (low cost supply switch)
• Mute facility.

handbook, halfpage
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
100 kΩ
• External timing circuit (see Fig.3).
MGA708
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.

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).
Diagnostic output (pin 16)
DYNAMIC 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 Figs 4 and 5).
During this short-circuit condition, pin 16 is LOW for 20 ms
and HIGH for 50 µs (see Fig.6).
The power dissipation in any short-circuit condition is
very low.
TEMPERATURE DETECTION
SHORT-CIRCUIT PROTECTION
When the virtual junction temperature Tvj reaches 150 °C,
pin 16 will be active LOW.
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.
OPEN-COLLECTOR OUTPUT
Pin 16 is an open-collector output, which allows pin 16 of
more devices being tied together.
When a short-circuit across the load of one or more
channels occurs the output stages are switched off during
