The TDA7303 is a digital controlled stereo audio processor with loudness function, suitable for car radios, Hi-Fi and portable systems. It features selectable input gain and external loudness function. Control is accomplished by serial I2C bus microprocessor interface.
The TDA7303 is a digital controlled stereo audio processor designed for quality audio applications in car radios, Hi-Fi, and portable systems. It functions as a volume, tone (bass and treble), balance (left/right), and fader (front/rear) processor. The device features selectable input gain, an external loudness function, and four independent speaker attenuators for balance and fader facilities.
