Stereo/dual TV sound decoder circuit
TDA3803A
GENERAL DESCRIPTION
The TDA3803A is a stereo/dual TV sound decoder circuit with static switching for processing two AF signals in TV and
VCR equipment. The LOW/HIGH static switching signals control the AF output selector. Two operational amplifiers
perform bandpass filtering of the identification signals.
Features
• Amplification of the two AF input signals by integrated operational amplifiers
• Low distortion stereo de-matrix
• All operational amplifiers offset compensated
• De-emphasis with operational amplifiers, preferably applied to the output terminals
• Two output ports each with two channels for headphones and loudspeakers
• Dual sound information at one port, each port individually switchable from sound I to sound II and sound II to sound I
• Mute function; while mute is active, it is possible to connect an external mono AF input signal to pin 10 appearing at
pins 20 to 23.
• Identification without additional signals (horizontal etc.)

Notes to the characteristics
1. An input signal at pin 10 appears at pins 20 to 23 if the mute input (pin 18) is activated (V18-12 ≥ 2 V).
2. With mute (pin 18) ON both LEDs (pin 14 and 15) are switched OFF.
3. Pin 14 and 15 are also suitable as output switches to control TDA3810.
At LED OFF and I14, 15 ≤ 100 µA, then V14, 15-12 ≤ 200 mV.

with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
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.
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.
Repairing soldered joints
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).
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.
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
