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

SDIP30

! Volume control in 1-dB steps

! Two speaker attenuators:

high-quality audio applications in car-radio and

Hi-Fi systems. Selectable input gain is provided.

All the functions are controlled by serial bus.

– two independent speaker controls in 1-dB

steps for balance facility

– independent mute function

The AC signal setting is obtained by resistor

networks and switches combined with operational

amplifiers.

! All functions are programmable via serial bus.

The TDA7439 employs BIPOLAR/CMOS

technology to provide low distortion, low noise

and DC stepping.

Description

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

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