TDA7439DS Three-band digitally-controlled audio processor Features ! Input multiplexer – four stereo inputs – selectable input gain for optimal adaptation to different sources ! Single stereo output ! Treble, mid-range and bass control in 2-dB steps ! Volume control in 1-dB steps ! Two speaker attenuators: – two independent speaker controls in 1-dB steps for balance facility – independent mute function ! All functions are programmable via serial bus. Description 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 networks and switches combined with operational amplifiers. The TDA7439DS employs BIPOLAR/CMOS technology to provide low distortion, low noise and DC stepping. Table 1. Device summary Order codes TDA7439DS TDA7439DS13TR SO28 SO.
