FUNCTIONAL DESCRIPTION
The TDA7052 is a mono output amplifier designed for battery-fed portable audio applications, such as tape recorders
and radios.
The gain is fixed internally at 40 dB. A large number of tape recorders and radios are still designed for mono sound, plus
a space-saving trend by reduction of the number of battery cells. This means a decrease in supply voltage which results
in an reduction of output power. To compensate for this reduction, the TDA7052 uses the Bridge-Tied-Load principle
(BTL) which can deliver an output power of 1,2 W (THD = 10%) into an 8
load with a power supply of 6 V. The load
can be short-circuited at each signal excursion.

; f = 1 kHz; T

C; unless otherwise specified.
Notes to the characteristics
1. The unweighted RMS noise output voltage is measured at a bandwidth of 60 Hz to 15 kHz with a source impedance
(R
S
) of 5 k
.
2. The RMS noise output voltage is measured at a bandwidth of 5 kHz with a source impedance of 0
and a frequency
of 500 kHz. With a practical load (R = 8
; L = 200
H) the noise output current is only 100 nA.
3. Ripple rejection is measured at the output with a source impedance of 0
and a frequency between 100 Hz and
10 kHz. The ripple voltage = 200 mV (RMS value) is applied to the positive supply rail.

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" (order code 9398 652 90011).
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.
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
stg 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.
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.
