TDA7303
Digital controlled stereo audio processor with loudness
Features
■ Input multiplexer:
– 3 stereo inputs
– Selectable input gain for optimal adaption
to different sources
■ Volume control in 1.25dB steps
■ Loudness function
■ Treble and bass controL
■ Four speaker attenuatorS:
– 4 independent speakers control in 1.25dB
steps for balance and fader facilities
– Independent mute function
■ All functions programmable via serial I²C bus
Description
The TDA7303 is a volume, tone (bass and treble)
balance (Left/Right) and fader (front/rear)
processor for quality audio applications in car
radio, Hi-Fi and portable systems.
SO-28
Selectable input gain and external loudness
function are provided. Control is accomplished by
serial I²C bus microprocessor interface.
The AC signal setting is obtained by resistor
networks and switches combined with operational
amplifiers.
Thanks to the used BIPOLAR/CMOS Tecnology,
Low Distortion, Low Noise and Low DC stepping
are obtained.
