FEATURES
GENERAL DESCRIPTION
• Low dissipation due to switching from Single-Ended
(SE) to Bridge-Tied Load (BTL) mode
The TDA1564 is a monolithic power amplifier in a 17-lead
single-in-line (SIL) plastic power package. It contains two
identical 25 W amplifiers. The dissipation is minimized by
switching from SE to BTL mode, only when a higher output
voltage swing is needed. The device is primarily
developed for car radio applications.

FUNCTIONAL DESCRIPTION
The heatsink has to be designed for use with music
signals. With such a heatsink, the thermal protection will
disable the BTL mode when the junction temperature
exceeds 150 °C. In this case, the output power is limited to
5 W per amplifier.
The TDA1564 contains two identical amplifiers with
differential inputs. At low output power [up to output
amplitudes of 3 V (RMS) at VP = 14.4 V], the device
operates as a normal SE amplifier. When a larger output
voltage swing is needed, the circuit switches internally to
BTL operation.
The gain of each amplifier is internally fixed at 26 dB. The
device can be switched to the following modes via the
MODE pin:
With a sine wave input signal, the dissipation of a
conventional BTL amplifier (up to 2 W output power) is
more than twice the dissipation of the TDA1564 (see
Fig.12).
• Standby with low standby current (< 50 µA)
• Mute condition, DC adjusted
• On, operation.
In normal use, when the amplifier is driven with music-like
signals, the high (BTL) output power is only needed for a
small percentage of time. Assuming that a music signal
has a normal (Gaussian) amplitude distribution, the
dissipation of a conventional BTL amplifier with the same
output power is approximately 70 % higher (see Figs 13
and 14.
The device is fully protected against a short-circuit of the
output pins to ground and to the supply voltage. It is also
protected against a short-circuit of the loudspeaker and
against high junction temperatures. In the event of a
permanent short-circuit condition to ground or the supply
voltage, the output stage will be switched off, causing low
dissipation. With a permanent short-circuit of the

TDA1564
loudspeaker, the output stage will be repeatedly switched
on and off. The duty cycle in the ‘on’ condition is low
enough to prevent excessive dissipation.
– When a short-circuit occurs (for at least 10 ms) at the
outputs to ground or the supply voltage, the output
stages are switched off to prevent excessive
dissipation; the outputs are switched on again
approximately 500 ms after the short-circuit is
removed, during this short-circuit condition the
protection pin is LOW
The device also has two independent DC offset detection
circuits that can detect DC output voltages across the
speakers. With a DC offset greater than 2 V, a warning is
given on the diagnostic pin. There will be no internal
shutdown with DC offsets.
– When a short-circuit occurs across the load (for at
least 10 ms), the output stages are switched off for
approximately 500 ms; after this time, a check is
made to see whether the short-circuit is still present
When the supply voltage drops below 6 V (e.g. engine
start), the circuit mutes immediately, avoiding clicks from
the electronic circuit preceding the power amplifier.
– The power dissipation in any short-circuit condition is
very low.
The voltage of the SE electrolytic capacitor (pin 4) is kept
at 0.5VP by means of a voltage buffer (see Fig.2). The
value of this capacitor has an important influence on the
output power in SE mode, especially at low signal
frequencies. A high value is recommended to minimize
dissipation at low frequencies.
• During start-up/shutdown, when the product is internally
muted
• Temperature prewarning:
– A prewarning (junction temperature > 145 °C)
indicates that the temperature protection will become
active. The prewarning can be used to reduce the
input signal and thus reduce the power dissipation.
The diagnostic output is an open-collector output and
requires a pull-up resistor. It gives the following outputs:
• Clip detection at THD = 2.5 %
• Short-circuit protection:
• Offset detection:
– One of the channels has a DC output voltage greater
than 2 V.

There are two parameters that determine the size of the
heatsink. The first is the rating for the virtual junction
temperature and the second is the ambient temperature at
which the amplifier must still deliver its full power in the
BTL mode.

APPLICATION NOTES
Advantages of high efficiency
1. Power conversion improvement (power supply):
Usually, the fact that the reduction of dissipation is
directly related to supply current reduction, is
neglected. One advantage is less voltage drop in the
whole supply chain. Another advantage is less stress
for the coil in the supply line. Even the adapter or
supply circuit remains cooler than before due to the
reduced heat dissipation in the whole chain because
more supply current will be converted into output
power.

2. Power dissipation reduction: This is the best known
advantage of high efficiency amplifiers.
3. Heatsink size reduction: The heatsink size of a
conventional amplifier may be reduced with
approximately 50 % at Vp = 14.4 V when the TDA1564
will be used. In that case, the maximum heatsink
temperature will remain the same.

4. Heatsink temperature reduction: The power
dissipation and the thermal resistance of the heatsink
determine the heatsink temperature rise.
Fig.25 Heatsink design.
When the same heatsink size is used from a conventional
amplifier, the maximum heatsink temperature decreases
and also the maximum junction temperature, which
extends the life of this semiconductor device. The
maximum dissipation with music-like input signals
decreases by 40 %.
Advantage of the concept used by TDA1564
The TDA1564 is highly efficient under all conditions,
because it uses a single-ended capacitor to create a
non-dissipating half supply voltage. Other concepts rely on
the fact that both input signals are the same in amplitude
and phase. With the concept of a SE capacitor it means
that it doesn’t matter what kind of signal processing is done
on the input signals. For example, amplitude difference,
phase shift or delays between both input signals, or other
DSP processing, have no impact on the efficiency.
It is clear that the use of the TDA1564 saves a significant
amount of energy. The maximum supply current
decreases by approximately 32 %, that reduces the
dissipation in the amplifier as well as in the whole supply
chain. The TDA1564 allows a heatsink size reduction of
approximately 50 % or the heatsink temperature
decreases by 40 % when the heatsink size hasn’t been
changed.

SOLDERING
Introduction
cooling) vary between 100 and 200 seconds depending
on heating method.
Typical reflow peak temperatures range from
215 to 270 °C depending on solder paste material. The
top-surface temperature of the packages should
preferably be kept:
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”
(document order number 9398 652 90011).
• below 225 °C (SnPb process) or below 245 °C (Pb-free
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mount components are mixed on
one printed-circuit board. Wave soldering can still be used
for certain surface mount ICs, but it is not suitable for fine
pitch SMDs. In these situations reflow soldering is
recommended. Driven by legislation and environmental
forces the worldwide use of lead-free solder pastes is
increasing.
process)
– for all the BGA, HTSSON..T and SSOP-T packages
– for packages with a thickness ≥ 2.5 mm
– for packages with a thickness < 2.5 mm and a
volume ≥ 350 mm3 so called thick/large packages.
• below 240 °C (SnPb process) or below 260 °C (Pb-free
process) for packages with a thickness < 2.5 mm and a
volume < 350 mm3 so called small/thin packages.
Through-hole mount packages
Moisture sensitivity precautions, as indicated on packing,
must be respected at all times.
SOLDERING BY DIPPING OR BY SOLDER WAVE
Typical dwell time of the leads in the wave ranges from
3 to 4 seconds at 250 °C or 265 °C, depending on solder
material applied, SnPb or Pb-free respectively.
WAVE SOLDERING
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
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 (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.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
MANUAL SOLDERING
• For packages with leads on two sides and a pitch (e):
Apply the soldering iron (24 V or less) to the lead(s) of the
package, either 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
– larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
300 and 400 °C, contact may be up to 5 seconds.
Surface mount packages
The footprint must incorporate solder thieves at the
downstream end.
REFLOW SOLDERING
• For packages with leads on four sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
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.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be

type oven. Throughput times (preheating, soldering and

applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured.
Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 °C or 265 °C, depending on solder material
applied, SnPb or Pb-free respectively.
A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications.
MANUAL SOLDERING
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron
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.

Notes
1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note” (AN01026); order a copy
from your Philips Semiconductors sales office.
2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.
3. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
4. Hot bar soldering or manual soldering is suitable for PMFP packages.
5. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account
be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature
exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package body peak temperature
must be kept as low as possible.
6. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder
cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,
the solder might be deposited on the heatsink surface.
7. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.

8. Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is definitely not
suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
9. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than
0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
10. Hot bar or manual soldering is suitable for PMFP packages.
11. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted
on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar
soldering process. The appropriate soldering profile can be provided on request.
