FUNCTIONAL DESCRIPTION
The TDA7053 is a stereo output amplifier, with an internal gain of 39 dB, which is primarily for use in portable audio
applications but may also be used in mains-fed applications. The current trends in portable audio application design is
to reduce the number of batteries which results in a reduction of output power when using conventional output stages.
The TDA7053 overcomes this problem by using the Bridge-Tied-Load (BTL) principle and is capable of delivering 1.2 W
into an 8 Ω load (V
supply voltage 13. OUT1B output 1 (negative)
= 6 V). The load can be short-circuited under all input conditions.

Notes to the characteristics
1. With a practical load the total quiescent current depends on the offset voltage.
2. Ripple rejection measured at the output with R
= 0Ωand f = 100 Hz to 10 kHz. The ripple voltage (200 mV) is applied
S
to the positive supply rail.
3. RS = 5 kΩ.
4. The noise output voltage (RMS value) is measured with RS= 5 kΩ, unweighted and a bandwidth of 60 Hz to 15 kHz.
5. The noise output voltage (RMS value) is measured with RS = 0 Ω and f = 500 kHz with 5 kHz bandwidth. If RL= 8 Ω
and LL= 200 µH the noise output current is only 100 nA.

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).
TDA7053
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.
