7. Functional description
The TDA8566 contains 2 identical amplifiers and can be used for BTL applications. The
gain of each amplifier is fixed at 26 dB. Special features of this device are:
• Mode select switch
• Clip detection
• Short-circuit diagnostic
• Temperature pre-warning
• Open-collector diagnostic outputs
• Differential inputs
7.1 Mode select switch (pin MODE)
• Standby: low supply current
• Mute: input signal suppressed
• Operating: normal on condition
Since this pin has a very low input current (< 40 µA), a low-cost supply switch can be
applied. To avoid switch-on plops, it is advisable to keep the amplifier in the mute mode for
a period of ≥ 150 ms (charging the input capacitors at pins IN1+, IN1−, IN2+ and IN2−).
This can be realized by using a microcontroller or by using an external timing circuit as
illustrated in Figure 8.
7.2 Clip detection (pin CLIP)
When clipping occurs at one or more output stages, the dynamic distortion detector
becomes active and pin CLIP goes LOW. This information can be used to drive a sound
processor or a DC volume control to attenuate the input signal and so limit the level of
distortion. The output level of pin CLIP is independent of the number of channels that are
being clipped. The clip detection circuit is disabled in a short-circuit condition, so if a fault
condition occurs at the outputs, pin CLIP will remain at a HIGH level. The clip detection
waveforms are illustrated in Figure 5.

7.3 Short-circuit diagnostic (pin DIAG)
When a short-circuit occurs at one or more outputs to ground or to the supply voltage, the
output stages are switched off until the short-circuit is removed and the device is switched
on again (with a delay of approximately 20 ms after the removal of the short-circuit).
During this short-circuit condition, pin DIAG is continuously LOW.
When a short-circuit occurs across the load of one or both channels, the output stages are
switched off for approximately 20 ms. After that time the load condition is checked during
approximately 50 µs to see whether the short-circuit is still present. Due to this duty cycle
of 50 µs/20 ms the average current consumption during the short-circuit condition is very
low (approximately 40 mA). During this condition, pin DIAG is LOW for 20 ms and HIGH
for 50 µs; see Figure 6. The power dissipation in any short-circuit condition is very low.

7.4 Temperature pre-warning (pin DIAG)
When the virtual junction temperature (Tvj) reaches 145 °C, pin DIAG will become
continuously LOW.
7.5 Open-collector diagnostic outputs
Pins DIAG and CLIP are open-collector outputs, therefore more devices can be tied
together. Pins DIAG and CLIP can also be tied together. An external pull-up resistor is
required.

7.6 Differential inputs
The input stage is a high-impedance fully differential balanced input stage that is also
capable of operating in a single-ended mode with one of the inputs capacitively coupled to
an audio ground. It should be noted that if a source resistance is added (input voltage
dividers) the CMRR degrades to lower values.

12. Application information
12.1 Diagnostic output
Special care must be taken in the PCB layout to separate pin CLIP from
pins IN1+, IN1−, IN2+ and IN2− to minimize the crosstalk between the CLIP output and
the inputs.
12.2 Mode select switch
To avoid switch-on plops, it is advisable to keep the amplifier in the mute mode during
≥ 150 ms (charging of the input capacitors at pins IN1+, IN1−, IN2+ and IN2−). The circuit
in Figure 8 slowly ramps-up the voltage at the mode select switch pin when switching on
and results in fast muting when switching off.

15. Soldering
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
15.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
15.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
• Board specifications, including the board finish, solder masks and vias
• Package footprints, including solder thieves and orientation
• The moisture sensitivity level of the packages
• Package placement
• Inspection and repair
• Lead-free soldering versus PbSn soldering
15.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities

15.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 13) than a PbSn process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 9 and 10

Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 13.
