Overview
TDA7300 DIGITAL CONTROLLED STEREO AUDIO PROCESSOR SINGLE SUPPLY OPERATION FOUR STEREO INPUT SOURCE SELECTION MONO INPUT TREBLE, BASS, VOLUME, AND BALANCE CONTROL FOUR INDEPENDENT SPEAKER CONTROL (FRONT/REAR) SINGLE SUPPLY OPERATION ALL FUNCTIONS PROGRAMMABLE VIA SERIAL BUS VERY LOW NOISE AND VERY LOW DISTORTION POP FREE SWITCHING DESCRIPTION The TDA7300 is a volume, tone (bass and treble), balance (left/right) and fader (front/rear) procesBLOCK DIAGRAM DIP28 SO28 ORDERING NUMBERS: TDA7300 TDA7300D sor for high quality audio applications in car radio and Hi-Fi systems.
Control is accomplished by serial bus microprocessor interface.
The AC signal setting is obtained by resistor networks and analog switches combined with operational amplifiers.
The results are: low noise, low distortion and high dynamic range.
