DIGITAL CONTROLLED STEREO AUDIO PROCESSORWITH LOUDNESS
TDA7313NDIGITAL CONTROLLED STEREO AUDIO PROCESSOR
WITH LOUDNESS
INPUT MULTIPLEXER:
- 3 STEREO INPUTS
- SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTION TO DIFFERENT SOURCES
LOUDNESS FUNCTION
VOLUME CONTROL IN 1.25dB STEPS
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 SE-
RIAL I2 C BUS
DESCRIPTIONThe TDA7313N is a volume, tone (bass and treble)
balance (Left/Right) and fader (front/rear) processor
for quality audio applications in car radio and Hi-Fi
systems.
Selectable input gain and external loudness function
are provided. Control is accomplished by serial2 C 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.

Notes:(1) Bass and Treble response see attached diagram (fig.16). The center frequency and quality of the resonance behaviour can be choosen by
the external circuitry. A standard first order bass response can be realized by a standard feedback network
(2) The selected input is grounded thru the 2.2μF capacitor.
