TDA7439DS, Three-band digitally-controlled audio processor

The TDA7439DS is a volume, tone (bass, mid-range and treble) and balance (left/right) SO28 processor for quality audio applications in car-radio and Hi-Fi systems.

Selectable input gain is provided.

All the functions are controlled by serial bus.

The AC signal setting is obtained by resistor networ
