Description

The TDA7438 is a volume tone (bass, middle and treble) balance (Left/Right) processor for quality audio applications in car-radio and Hi-Fi systems.

Selectable input gain is provided. Control of all the functions is accomplished by serial bus.

The TDA7438 AC signal setting is obtained by resistor networks and switches combined with operational amplifiers.

Thanks to the used BIPOLAR/CMOSTechnology, Low Distortion, Low Noise and DC stepping are obtained.
