FUNCTIONAL DESCRIPTION
This can be achieved by:
• Microprocessor control
The TDA8511J contains four identical amplifiers and can
be used for single-ended applications. The gain of each
amplifier is fixed at 20 dB. Special features of the device
are:
• External timing circuit (see Fig.7).
Diagnostic output (pin 16)
• Mode select switch (pin 14)
• Diagnostic output (pin 16).
DYNAMIC DISTORTION DETECTOR (DDD)
At the onset of clipping of one or more output stages, the
dynamic distortion detector becomes active and pin 16
goes LOW. This information can be used to drive a sound
processor or DC volume control to attenuate the input
signal and thus limit the distortion. The output level of
pin 16 is independent of the number of channels that are
clipping (see Fig.3).
Mode select switch (pin 14)
• Low standby current (<100 µA)
• Low switching current (low cost supply switch)
• Mute facility.
To avoid switch-on plops, it is advised to keep the amplifier
in the mute mode during ≥100 ms (charging of the input
capacitors at pin 1, 3, 15 and pin 17).

SHORT-CIRCUIT PROTECTION
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 removal of the short-circuit. During this
short-circuit condition, pin 16 is continuously LOW.
MGA706
V
handbook, halfpage
O
0
When a short-circuit across the load of one or more
channels occurs the output stages are switched off during
approximately 20 ms. After that time it 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 this short-circuit condition is
very low (approximately 40 mA).
V

t
During this short-circuit condition, pin 16 is LOW for 20 ms
and HIGH for 50 µs (see Fig.4).
The power dissipation in any short-circuit condition is very
low.
Fig.3 Distortion detector waveform.
TEMPERATURE DETECTION
OPEN COLLECTOR OUTPUT
When the virtual junction temperature Tvj reaches 150 °C,
pin 16 will be active LOW.
Pin 16 is an open collector output, which allows that more
devices can be connected together (pins 16).

SOLDERING
The total contact time of successive solder waves must not
exceed 5 seconds.
Introduction to soldering through-hole mount
packages
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.
This text gives a brief insight to wave, dip and manual
soldering. 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).
Wave soldering is the preferred method for mounting of
through-hole mount IC packages on a printed-circuit
board.
Manual soldering
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
Soldering by dipping or by solder wave
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joints for more than 5 seconds.
300 and 400 °C, contact may be up to 5 seconds.
