2 W BTL audio amplifier TDA8543

FUNCTIONAL DESCRIPTION

The TDA8543(T) is a BTL audio power amplifier capable
of delivering an output power between 1 and 2 W,
depending on supply voltage, load resistance
and package. Using the MODE pin the device can
be switched to standby and mute condition. The device
is protected by an internal thermal shutdown protection
mechanism.
The gain can be set within a range from 6 dB to 30 dB
by external feedback resistors.

Power amplifier

The power amplifier is a Bridge Tied Load (BTL) amplifier
with a complementary PNP-NPN output stage.

The voltage loss on the positive supply line is
the saturation voltage of a PNP power transistor,
on the negative side the saturation voltage of an
NPN power transistor.

Mode select pin

The device is in standby mode (with a very low current
consumption) if the voltage at the MODE
pin is >(V

CC

− 0.5 V), or if this pin is floating. At a MODE
voltage level of less than 0.5 V the amplifier is fully
operational.
In the range between 1.5 V and V

CC

− 1.5 V the amplifier
is in mute condition. The mute condition is useful to
suppress plop noise at the output, caused by charging of
the input capacitor.

LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 134).

QUALITY SPECIFICATION

“SNW-FQ-611-E”

. The number of the quality specification can be found in the

Notes to the AC characteristics

1. Gain of the amplifier is in test circuit of Fig.4.

2. The noise output voltage is measured at the output in a frequency range from 20 Hz to 20 kHz (unweighted), with
a source impedance of RS=0Ω at the input.

3. Supply voltage ripple rejection is measured at the output, with a source impedance of RS=0Ω at the input.
The ripple voltage is a sine wave with a frequency of 1 kHz and an amplitude of 100 mV (RMS), which is applied
to the positive supply rail.

4. Supply voltage ripple rejection is measured at the output, with a source impedance of RS=0Ω at the input.
The ripple voltage is a sine wave with a frequency between 100 Hz and 20 kHz and an amplitude of 100 mV (RMS),
which is applied to the positive supply rail.

5. Output voltage in mute position is measured with an input voltage of 1 V (RMS) in a bandwidth of 20 kHz, so including
noise.

TEST AND APPLICATION INFORMATION
Test conditions

Because the application can be either Bridge Tied Load
(BTL) or Single-Ended (SE), the curves of each application
are shown separately.

The thermal resistance = 55 K/W for the DIP16 envelope;
the maximum sine wave power dissipation
for T

=25°C is:

For T

=60°C the maximum total power dissipation is:

=25°C if not specially mentioned, VCC=5V,
f = 1 kHz, RL=8Ω, Gv= 20 dB, audio band-pass
22 Hz to 22 kHz.

The BTL application diagram is shown in Fig.4.
The quiescent current has been measured without

any load impedance. The total harmonic distortion
as a function of frequency was measured with a low-pass
filter of 80 kHz. The value of capacitor C2 influences
the behaviour of the SVRR at low frequencies, increasing
the value of C2 increases the performance of the SVRR.
The figure of the mode select voltage (Vms) as a function
of the supply voltage shows three areas; operating, mute
and standby. It shows, that the DC-switching levels
of the mute and standby respectively depends
on the supply voltage level.

The SE application diagram is shown in Fig.14.
The capacitor value of C3 in combination with the load

impedance determines the low frequency behaviour.
The total harmonic distortion as a function of frequency
was measured with low-pass filter of 80 kHz. The value
of capacitor C2 influences the behaviour of the SVRR
at low frequencies, increasing the value of C2 increases
the performance of the SVRR.

General remark

The frequency characteristic can be adapted
by connecting a small capacitor across the feedback
resistor. To improve the immunity of HF radiation in radio
circuit applications, a small capacitor can be connected
in parallel with the feedback resistor; this creates a
low-pass filter.

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”

(order code 9398 652 90011).

DIP

SOLDERING BY DIPPING OR BY WA VE
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.

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

stg max

). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.

R

EPAIRING 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.

SO

REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO

packages.
Reflow soldering requires solder paste (a suspension of

fine solder particles, flux and binding agent) to be applied

to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.

WAVE SOLDERING
Wave soldering techniques can be used for all SO

packages if the following conditions are observed:

• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.

• The longitudinal axis of the package footprint must be
parallel to the solder flow.

• The package footprint must incorporate solder thieves at
the downstream end.

During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.

A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

R

EPAIRING SOLDERED JOINTS

Fix the component by first soldering two diagonally­opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
