Overview
® TDA7403 BASIC SIGNAL PROCESSOR DEVICE INCLUDES AUDIO PROCESSOR, STEREO DECODER AND NOISEBLANKER HIGH PERFORMANCE SIGNAL PROCES- SOR WITH BASIC FUNCTIONS AM, FM, (MPX) AND CASSETTE INPUTS ) NO EXTERNAL COMPONENTS REQUIRED t(s FULLY PROGRAMMABLE VIA I2C BUS LOW DISTORTION AND NOISE duc DESCRIPTION ro The TDA7403 is a high performance signal procP essor specifically designed for car radio applicate tions focused on the low-end market.
le The device includes a complete audioprocessor and a stereo decoder with noiseblanker.
so Switched-capacitors design technique allows to b obtain all these features without external compoO nents or adjustments.
Using TDA7403 results is in a very performant low-cost signal processing t(s) - BLOCK DIAGRAM SO20 ORDERING NUMBER: TDA7403D application The device is fully programmable by I2C bus interface allowing to customize key device parameters and especially filter characteristics.
The BICMOS process combined with the optimized signal processing assure low noise and low distortion performances.
