Overview
® TDA7315 DIGITAL CONTROLLED AUDIO PROCESSOR 1 STEREO INPUT LOUDNESS FUNCTION VOLUME CONTROL IN 1.
25dB STEPS TREBLE AND BASS CONTROL TWO SPEAKERS ATTENUATORS: - INDEPENDENT SPEAKERS CONTROL IN 1.
25dB STEPS - INDEPENDENT MUTE FUNCTION ALL FUNCTIONS PROGRAMMABLE VIA SERIAL BUS DESCRIPTION The TDA7315 is a volume, tone (bass and treble) balance (Left/Right) processor for quality audio applications in car radio and Hi-Fi systems.
Control is accomplished by serial bus microprocessor interface.
The AC signal settingis obtainedby resistor networks BLOCK DIAGRAM SO20 DIP 20 ORDERING NUMBER: TDA7315 (DIP 20) TDA7315D (SO 20) and switches combined with operational amplifiers.
Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
