FUNCTIONAL DESCRIPTION  
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.  
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.  
Mode select pin  
The device is in standby mode (with a very low current  
consumption) if the voltage at the MODE  
pin is >(VCC 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.  
The gain can be set within a range from 6 dB to 30 dB  
by external feedback resistors.  
Power amplifier  
In the range between 1.5 V and VCC 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.  
The power amplifier is a Bridge Tied Load (BTL) amplifier  
with a complementary PNP-NPN output stage.  
LIMITING VALUES  
In accordance with the Absolute Maximum Rating System (IEC 134).

-------  
1. Gain of the amplifier is 2 ×  
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 = 0 Ω at the input.  
3. Supply voltage ripple rejection is measured at the output, with a source impedance of RS = 0 Ω 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 = 0 Ω 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  
SE application  
Tamb = 25 °C if not specially mentioned, VCC = 7.5 V,  
f = 1 kHz, RL = 4 Ω, Gv = 20 dB, audio band-pass  
22 Hz to 22 kHz.  
Because the application can be either Bridge Tied Load  
(BTL) or Single-Ended (SE), the curves of each application  
are shown separately.  
The SE application diagram is shown in Fig.14.  
The thermal resistance = 55 K/W for the DIP16 envelope;  
the maximum sine wave power dissipation  
for Tamb = 25 °C is:  
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.  
150 25  
= 2.27 W  
----------------------  
55  
For Tamb = 60 °C the maximum total power dissipation is:  
150 60  
= 1.63 W  
----------------------  
55  
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.  
See the power derating curve illustrated in Fig.3.  
BTL application  
Tamb = 25 °C if not specially mentioned, VCC = 5 V,  
f = 1 kHz, RL = 8 Ω, 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.

SOLDERING  
Introduction  
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.  
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.  
Preheating is necessary to dry the paste and evaporate  
the binding agent. Preheating duration: 45 minutes at  
45 °C.  
WAVE SOLDERING  
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).  
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.  
DIP  
SOLDERING BY DIPPING OR BY WAVE  
The longitudinal axis of the package footprint must be  
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.  
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.  
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 (Tstg 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.  
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.  
REPAIRING SOLDERED JOINTS  
A mildly-activated flux will eliminate the need for removal  
of corrosive residues in most applications.  
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.  
REPAIRING SOLDERED JOINTS  
Fix the component by first soldering two diagonally-  
opposite 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.  
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.
