描述 Description

The TDA7439DS is a volume, tone (bass, mid-range and treble) and balance (left/right) 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 networks and switches combined with operational amplifiers.

The TDA7439DS employs BIPOLAR/CMOS technology to provide low distortion, low noise and DC stepping.
