TDA7439

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 TDA7439 is a volume, tone (bass, mid-range

and treble) and balance (left/right) processor for

high-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 TDA7439 employs BIPOLAR/CMOS

technology to provide low distortion, low noise

and DC stepping.
