TDA7412 Datasheet Carradio Signal Processor

Manufacturer: STMicroelectronics

Overview: TDA7412 CARRADIO SIGNAL PROCESSOR s s s s s s s s s s s 3 STEREO INPUTS 3 MONO INPUTS DYNAMIC-PRESSION-STAGE FOR CD SOFTSTEP-VOLUME BASS, TREBLE AND LOUDNESS CONTROL VOICE-BAND-FILTER DIRECT MUTE AND SOFTMUTE INTERNAL.

General Description

The device includes a high performance audioprocessor and a stereodecoder-noiseblanker bination with the whole low frequency signal processing necessary for state-of-the-art as well as future carradios.

The digital control allows a programming in a wide range of all the filter characteristics.

Also the stereodecoder part offers several possibilities of programming especially for the adaptation to different IF-devices.
