TDA7420

The TDA7420 I²C bus controlled multifunction audio processor contains all signal processing blocks of a high performance car radio, including audio processor, stereodecoder, noise blanker, different mute functions,cassette preamplifier andAMS function.

The use of BICMOS technology allows the implementation of several filter functions with switched capacitor techniques like fully integrated, adjustment free PLL Loop filter, pilot detector with integrator.

This minimizes the number of external components of TDA7420.

Due to a highly linear signal processing, using CMOS-switching techniques instead of standard bipolar multipliers, very low distortion and very low noise are obtained also in the stereodecoder part.

Very low DC stepping is obtained by use of the BICMOS technology.
