FUNCTIONAL DESCRIPTION
The TDA1553Q contains two identical amplifiers with differential input stages and can be used for bridge applications.
The gain of each amplifier is fixed at 26 dB. Special features of this device are:
Mute/stand-by switch
• low stand-by current (< 100 µA)
• low mute/stand-by switching current (low cost supply switch)
• mute facility.
positive supply voltage 2
Loudspeaker protection
When a short-circuit to ground is made, which forces a DC voltage across the loudspeaker of ≥ 1 V, a built-in protection
circuit becomes active and limits the DC voltage across the loudspeaker to ≤ 1 V. The delay time of the protection circuit
can be controlled by an external capacitor connected to pin 12.

SOLDERING
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.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
“IC Package Databook”
our
Soldering by dipping or by wave
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.
(order code 9398 652 90011).
TDA1553Q
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 (T
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Repairing soldered joints
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.
