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.
