sound circuit
DESCRIPTION
The TDA3810 integrated circuit provides spatial, stereo and pseudo-stereo sound for radio and television equipment.
Features
• Three switched functions:
– spatial (widened stereo image)
– stereo
– pseudo-stereo (artificial stereo from a mono source)
• Offset compensated operational amplifiers to reduce switch noise
• LED driver outputs to facilitate indication of selected operating mode
• Start/stop circuit to reduce switch noise and to prevent LED-flicker
• TTL-compatible control inputs

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
“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

(order code 9398 652 90011).

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
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.
