TDA1565TH
FUNCTIONAL DESCRIPTION
The TDA1565TH contains two identical amplifiers with
differential inputs. At low output power (output amplitudes
of up to 3 V (RMS) at VP = 14.4 V), the device operates as
a normal SE amplifier. When a larger output voltage swing
is required, the circuit automatically switches internally to
BTL operation.
V
MODE
handbook, halfpage
18
(V)
With a sine wave input signal, the power dissipation of a
conventional BTL amplifier with an output power of up to
3 W is more than twice the power dissipation of the
TDA1565TH (see Fig.10).
Operating
4
During normal use, when the amplifier is driven by typical
variable signals such as music, 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 power dissipation of a
conventional BTL amplifier with the same output power is
approximately 70 % higher (see Fig.11).
3
Mute
2
1
Standby
0
The heatsink must be designed for music signal operation.
When such a heatsink is used, the IC’s thermal protection
will disable the BTL mode when the junction temperature
exceeds 150 °C. In this case the output power is limited to
10 W per amplifier. The gain of each amplifier is internally
fixed at 26 dB.
MGR176
Fig.3
Switching levels of the mode select pin
(pin MODE).
The device can be switched to any of the following modes
by applying the appropriate voltage to the MODE pin (see
Fig.3):
• Standby with low standby current (less than 50 µA)
The diagnostic output indicates the following conditions:
• Mute condition; DC adjusted
• Clip detection at 2.5 % THD (see Fig.4)
• On, operation.
• Short-circuit protection (see Fig.5):
The device is fully protected against a short-circuit of the
output pins to ground or to the supply voltage. It is also
protected against a loudspeaker short-circuit and against
high junction temperatures. In the event of a permanent
short-circuit condition, the output stage is repeatedly
switched on and off with a low duty-cycle resulting in low
power dissipation.
– When an output short-circuit occurs (for at least
10 µs); the output stages are switched off for approx.
500 ms, after which time the outputs are checked to
see if a short-circuit condition still exists. During any
short-circuit condition, the power dissipation is very
low. During a short-circuit condition pin DIAG is at
logic LOW.
• Start-up/shutdown; when the product is internally muted
When the supply voltage drops below 6 V (e.g. vehicle
engine start), the circuit is immediately muted to prevent
audible ‘clicks’ that may be produced in the electronic
circuitry preceding the power amplifier.
• Thermal protection pre-warning:
– If the junction temperature rises above 145 °C but is
below the thermal protection temperature of 150 °C,
the diagnostic output indicates that the thermal
protection condition is about to become active. This
pre-warning can be used by another device to reduce
the amplitude of the input signal which would reduce
the power dissipation. The thermal protection
pre-warning is indicated by a logic LOW at pin DIAG.
The voltage across the SE electrolytic capacitor
connected to pin 16 is kept at 0.5 VP by a voltage buffer
(see Fig.1). The capacitor value has an important
influence on the output power in SE mode, especially at
low frequency signals; a high value is recommended to
minimize power dissipation at low frequencies.

Heatsink design
There are two parameters that determine the size of the
heatsink. The first is the rating of 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.

Example:
With a conventional BTL amplifier, the maximum power
dissipation for a typical signal, such as music (at each
amplifier) will be approximately two times 15 W. At a virtual
junction temperature of 150 °C and a maximum ambient
temperature of 65 °C, Rth(vj-c) = 1.8 K/W and
Rth(c-h) = 0.2 K/W. For a conventional BTL amplifier the
thermal resistance of the heatsink should be:
0

Compared to a conventional BTL amplifier, the
TDA1565TH has a higher efficiency. The thermal
resistance of the heatsink should be:

Application notes
ADVANTAGES OF HIGH EFFICIENCY
1. Power conversion improvement (power supply): The
fact that the reduction of power dissipation is directly
related to a reduction of supply current is often
neglected. One advantage is voltage is dropped over
the whole supply chain. Another advantage is reduced
stress for the coil in the supply line. Even the adapter
or supply circuit is cooler due to the reduced
dissipation of heat 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 size of heatsink for a
conventional amplifier can be reduced by
approximately 50 % at VP = 14.4 V when the
TDA1565TH is used. In this case, the maximum
heatsink temperature remains the same.

4. Heatsink temperature reduction: The power
dissipation and the thermal resistance of the heatsink
determine the rise in heatsink temperature.
Fig.23 Heatsink design.
If the same sized heatsink of a conventional amplifier is
used, the maximum heatsink temperature and the
maximum junction temperature both decrease, which
extends the life of the semiconductor device; the maximum
power dissipation for music, or similar input signals
decreases by 40 %.
ADVANTAGE OF THE CONCEPT USED BY TDA1565TH
Because the TDA1565TH uses a single-ended capacitor
to create a non-dissipating half supply voltage, it is highly
efficient under all conditions. Other design concepts rely
on the fact that both input signals have the same amplitude
and phase. Using a SE capacitor prevents any adverse
affects on efficiency that could result from any form of
processing that may have been applied to the input
signals, such as amplitude difference, phase shift or
delays between both input signals, or other DSP
processing.
It is clear that the use of the TDA1565TH saves a
significant amount of energy. The maximum supply current
decreases by approximately 32 %, which reduces the
power dissipation in the amplifier as well as in the whole
supply chain. The TDA1565TH allows the size of the
heatsink to be reduced by approximately 50 %, or the
temperature of the heatsink to be reduced by 40 % if the
size of the heatsink is unchanged.

If wave soldering is used the following conditions must be
observed for optimal results:
SOLDERING
Introduction to soldering surface mount packages
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
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).
• For packages with leads on two sides and a pitch (e):
– 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;
There is no soldering method that is ideal for all surface
mount IC packages. 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.
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
The footprint must incorporate solder thieves at the
downstream end.
Reflow soldering
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.
Driven by legislation and environmental forces the
worldwide use of lead-free solder pastes is increasing.
• 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.
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.
Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 and 200 seconds depending
on heating method.
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.
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:
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
• below 225 °C (SnPb process) or below 245 °C (Pb-free
process)
Manual soldering
– for all BGA, HTSSON-T and SSOP-T packages
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.
– 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.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.
Moisture sensitivity precautions, as indicated on packing,
must be respected at all times.
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.
To overcome these problems the double-wave soldering
method was specifically developed.

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. 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.
4. 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.
5. 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.
6. Wave soldering is suitable for LQFP, TQFP and QFP 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.
7. 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.
8. 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.
9. Hot bar or manual soldering is suitable for PMFP packages.
