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

DESCRIPTION
The TDA7315 is a volume, tone (bass and treble)
balance (Left/Right) processor for quality audio appli-
cations in car radio and Hi-Fi systems.
Control is accomplished by serial bus microprocessor
interface.
The AC signal settingis obtainedby resistor networks

and switches combined with operational amplifi-
ers.
Thanks to the used BIPOLAR/CMOS Technology,
Low Distortion, Low Noise and DC stepping are ob-
tained.
