FUNCTIONAL DESCRIPTION
Mode select pin
The TDA8541(T) is a BTL audio power amplifier capable
of delivering 1 W output power to an 8 Ω load at
THD = 10% using a 5 V power supply. 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.
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.
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.
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. The total voltage loss is <1 V and with a 5 V
supply voltage and an 8 Ω loudspeaker an output power of
1 W can be delivered.

to the DC output offset voltage divided by RL.

Notes
1. Gain of the amplifier is 2 × R2/R1 in test circuit of Fig.3.
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
SE application
Test conditions
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.13.
For Tamb = 60 °C the maximum total power dissipation 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 – 60
---------------------- = 0.9 W .
100
General remark
The thermal resistance = 100 K/W for the DIP8 envelope;
the maximum sine wave power dissipation for
Tamb = 25 °C is:
150 – 25
---------------------- = 1.25 W .
100
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 (56 kΩ); this creates a low-pass
filter.
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.3.
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
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.
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.
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
parallel to the solder flow.
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 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 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.
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.
