FEATURES
GENERAL DESCRIPTION
• DC volume control
The TDA7053A (2 × 1 W) and TDA7053AT (2 × 0.5 W) are
stereo BTL output amplifiers with DC volume control.
The devices are designed for use in TV and monitors, but
are also suitable for battery-fed portable recorders and
radios.
• Few external components
• Mute mode
• Thermal protection
• Short-circuit proof
Missing Current Limiter (MCL)
• No switch-on and switch-off clicks
• Good overall stability
• Low power consumption
• Low HF radiation
A MCL protection circuit is built-in. The MCL circuit is
activated when the difference in current between the
output terminal of each amplifier exceeds 100 mA
(typical 300 mA). This level of 100 mA allows for
headphone applications (single-ended).
• ESD protected on all pins.

For portable applications there is a trend to decrease the
supply voltage, resulting in a reduction of output power at
conventional output stages. Using the BTL principle
increases the output power.
FUNCTIONAL DESCRIPTION
The TDA7053A and TDA7053AT are stereo output
amplifiers with two DC volume control stages, designed for
TV and monitors, but also suitable for battery-fed portable
recorders and radios.
The maximum gain of the amplifier is fixed at 40.5 dB.
The DC volume control stages have a logarithmic control
characteristic. Therefore, the total gain can be controlled
from +40.5 to −33 dB.
In conventional DC volume control circuits the control or
input stage is AC coupled to the output stage via external
capacitors to keep the offset voltage low.
If the DC volume control voltage falls below 0.4 V, the
device will switch to the mute mode.
The two DC volume control stages are integrated into the
input stages so that no coupling capacitors are required
and a low offset voltage is still maintained. The minimum
supply voltage also remains low.
The amplifier is short-circuit protected to ground, VP and
across the load. A thermal protection circuit is also
implemented. If the crystal temperature rises above
150 °C the gain will be reduced, thereby reducing the
output power.
The BTL principle offers the following advantages:
• Lower peak value of the supply current
• The frequency of the ripple on the supply voltage is twice
the signal frequency.
Special attention is given to switch-on and switch-off
clicks, low HF radiation and a good overall stability.
Consequently, a reduced power supply with smaller
capacitors can be used which results in cost reductions.

TDA7053A:
Assume VP = 6 V and RL = 8 Ω.
The maximum sine wave dissipation is 2 × 0.9 W = 1.8 W.
The Rth j-a of the package is 50 K/W therefore Tamb(max) = 150 − (50 × 1.8) = 60 °C.
TDA7053AT:
Assume VP = 6 V and RL = 16 Ω.
The maximum sine wave dissipation is 2 × 0.46 W = 0.92 W.
The Rth j-a of the package is 95 K/W therefore Tamb(max) = 150 − (95 × 0.92) = 62.6 °C.

1. With a load connected to the outputs the quiescent current will increase, the maximum value of this increase being
equal to the DC output offset voltage divided by RL.
2. The noise output voltage (RMS value) at fi = 500 kHz is measured with RS = 0 Ω and bandwidth = 5 kHz.
3. 20 Hz to 300 kHz (typical).
4. The ripple rejection is measured with RS = 0 Ω and fi = 100 Hz to 10 kHz. The ripple voltage of 200 mV (RMS value)
is applied to the positive supply rail.
5. The channel unbalance is measured with VDC1 = VDC2
6. The channel unbalance at G1 = 0 dB is measured with VDC1 = VDC2
7. The noise output voltage (RMS value) is measured with RS = 5 kΩ unweighted.

The maximum input signal voltage is measured at
THD = 1% at the output with a voltage gain of 0 dB.
APPLICATION INFORMATION
The application diagram is illustrated in Fig.13.
To avoid instabilities and too high distortion, the input
ground and power ground must be separated as far as
possible and connected as close as possible to the IC.
Test conditions
Tamb = 25 °C unless otherwise specified; VP = 6 V;
The DC volume control can be applied in several ways.
Two possible circuits are shown below the main
application diagram. The circuits at the control pin will
influence the switch-on and switch-off behaviour and the
maximum voltage gain.
V
DC = 1.4 V; fi = 1 kHz; RL = 8 Ω.
The quiescent current has been measured without load
impedance.
The output power as a function of the supply voltage has
been measured at THD = 10%. The maximum output
power is limited by the maximum power dissipation and the
maximum available output current.
For single-end applications the output peak current must
not exceed 100 mA. At higher output currents the
short-circuit protection (MCL) will be active.

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
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.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
WAVE SOLDERING
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).
Wave soldering techniques can be used for all SO
packages if the following conditions are observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
DIP
SOLDERING BY DIPPING OR BY WAVE
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
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 package footprint must incorporate solder thieves at
the downstream end.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
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.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.
REPAIRING SOLDERED JOINTS
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
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.
REPAIRING SOLDERED JOINTS
Fix the component by first soldering two diagonally-
opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
SO
REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO
packages.
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
