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

SO28

! Volume control in 1-dB steps

! Two speaker attenuators:

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.

– two independent speaker controls in 1-dB

steps for balance facility

The AC signal setting is obtained by resistor

networks and switches combined with operational

amplifiers.

– independent mute function

! All functions are programmable via serial bus.

The TDA7439DS employs BIPOLAR/CMOS

technology to provide low distortion, low noise

and DC stepping.

Description

The TDA7439DS is a volume, tone (bass,

mid-range and treble) and balance (left/right)
