TDA7303
Digital controlled stereo audio processor with loudness
Features
■ Input multiplexer:
– 3 stereo inputs
– Selectable input gain for optimal adaptation
to different sources
■ Volume control in 1.25 dB steps
■ Loudness function
■ Treble and bass controL
■ Four speaker attenuators:
– 4 independent speakers control in 1.25d B
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.
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 technology, low
distortion, low noise and low DC stepping are
obtained.
