amplifier

FUNCTIONAL DESCRIPTION

The TDA8567Q contains four identical amplifiers which
can be used for bridge applications. The gain of each
amplifier is fixed at 26 dB.

Mode select switch (pin 15)

• Standby: low supply current (<100 µA)

• Mute: input signal suppressed

• Operating: normal on condition.

Since this pin has a low input current (<80 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 ≥150 ms (charging of the input
capacitors at pins 10, 11, 13 and 14). When switching
from standby to mute, the slope should be at least 18 V/s.

This can be realized by:

• Microprocessor control

• External timing circuit (see Fig.3).

TDA8567Q

HORT-CIRCUIT DIAGNOSTIC

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
10 ms after removal of the short-circuit. During this
short-circuit condition, pin 9 is continuously LOW.

When a short-circuit occurs across the load of one or more
channels, the output stages are switched off during
approximately 10 ms. After that time it is checked during
approximately 50 µs to determine whether the short-circuit
is still present.
Due to this duty cycle of 50 µs/10 ms the average current
consumption during this short-circuit condition is very low.

During this short-circuit condition, pin 9 is LOW for 10 ms
and HIGH for 50 µs (see Fig.5). The protection circuits of
all channels are coupled. This means that if a short-circuit
condition occurs in one of the channels, all channels are
switched off. Consequently, the power dissipation in any
short-circuit condition is very low.

Diagnostic output (pin 9)

D

YNAMIC DISTORTION DETECTOR (DDD)

At the onset of clipping of one or more output stages, the
dynamic distortion detector becomes active and pin 9
goes LOW. This information can be used to drive a sound
processor or DC volume control to attenuate the input
signal and so limit the distortion. The output level of pin 9
is independent of the number of channels that are clipping
(see Fig.4).

Special care must be taken in the PCB-layout to separate pin 9 from the pins10, 11 13 and 14 to minimize the crosstalk between the clip output
and the inputs.

To avoid switch-on plops, it is advised to keep the amplifier in the mute mode during a period of ≥ 150 ms (charging the input capacitors at pin
10, 11, 13 and 14).

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

“Data Handbook IC26; Integrated Circuit Packages”

(order code 9398 652 90011).

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.

TDA8567Q

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.
