Description
The TDA7439 is a volume tone (bass, middle, and treble) balance (Left/Right) processor for quality audio applications in carradio and HiFi systems. Selectable input gain is provided. Control of all the functions is accomplished by serial bus. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise, and DC stepping are obtained.
Features
Input Multiplexer:
4 Stereo Inputs
Selectable Input Gain for Optimal Adaptation to Different Sources
One Stereo Output
Treble, Middle, and Bass Control in 2.0dB Steps
Volume Control in 1.0dB Steps
Two Speaker Attenuators:
Two Independent Speaker Control in 1.0dB Steps for Balance Facility
Independent Mute Function
All Functions are Programmable via Serial Bus
Applications
Carradio and HiFi systems
