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)

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.
