FUNCTIONAL DESCRIPTION

The TDA8561Q contains four identical amplifiers and can

be used for Single-Ended (SE) or Bridge-Tied Load (BTL)

applications. The gain of each amplifier is fixed at 20 dB

(26 dB in BTL). Special features of the device are:

Mode select switch (pin 14)

•

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.11).

ISTORTION

D

ETECTOR

(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 3 and 4).

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 16 is continuously LOW.

When a short-circuit across the load of one or both

channels occurs the output stages are switched off for

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).

Fig.3

handbook, halfpage

VO

TDA8561Q

During this short-circuit condition, pin 16 is LOW for 20 ms

and HIGH for 50

µs

(see Fig.5).

The power dissipation in any short-circuit condition is very

low.
