Description

The TDA8440 is a versatile video/audio switch, intended to be used in CTV receivers equipped with an AUXILIARY VIDEO/AUDIO plug.

It provides two 3-state switches for audio channels and one 3-state switch for the video channel and a video amplifier with selectable gain (times 1 or times 2).

The integrated circuit of the TDA8440 can be used in conjunction with a microcontroller from the MAB8400 family, and is controlled via a bidirectional I²C bus. Sufficient sub-addressing is provided for the I²C bus mode. It can also be controlled directly by d.c. switching signals.
