Overview
TDA7303 Digital controlled stereo audio processor with loudness Features ■ Input multiplexer: www.
DataSheet4U.
com – 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 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.
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.
