STMicroelectronics TDA7340G
The TDA7340G I2C bus controlled audio signal processor contains all signal processing blocks of PQFP44 ORDERING NUMBER: TDA7340G a high performance car radio, including audioprocessor, stereodecoder, noise blanker, pause detector and different mute functions. 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 and pilot cancellation. This minimizes the number of external components.

DESCRIPTION
This minimizes the number of external components. 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. The audioprocessor contains several new features like softmute, zero-crossing mute and pause detector. Very low DC stepping is obtained by use of a BICMOS technology.
