DESCRIPTION

The TDA7403 is a high performance signal proc-

essor specifically designed for car radio applica-

tions focused on the low-end market.

The device includes a complete audioprocessor

and a stereo decoder with noiseblanker.

Switched-capacitors design technique allows to

obtain all these features without external compo-

nents or adjustments. Using TDA7403 results is

in a very performant low-cost signal processing

application

The device is fully programmable by I

2C bus in-

terface allowing to customize key device parame-

ters and especially filter characteristics.

The BICMOS process combined with the opti-

mized signal processing assure low noise and

low distortion performances.
