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.)

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

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 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.
