FUNCTIONAL DESCRIPTION
The TDA1553CQ 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 the device are:
3-state mode switch
• standby: low supply current (<100 µA)
• mute: input signal suppressed
• operating: normal on condition.
Loudspeaker protection
When a short-circuit to ground occurs, 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 ≤1V.
Pin 12 detects the status of the protection circuit (e.g. for
diagnostic purposes).

Short-circuit protection
If any output is short-circuited to ground during the standby
mode, it becomes impossible to switch the circuit to the
mute or operating condition. In this event the supply
current will be limited to a few milliamps.

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
our
“IC Package Databook”
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).
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.
