DIGITAL CONTROLLED STEREO AUDIO PROCESSOR
TDA7312DIGITAL CONTROLLED STEREO AUDIO PROCESSOR
INPUT MULTIPLEXER:
- 4 STEREO INPUTS
FOUR SELECTABLE ADDRESSES
TWO DIGITAL CONTROL OUTPUTS
INPUT AND OUTPUT FOR EXTERNAL
EQUALIZER OR NOISE REDUCTION SYS-
TEM
VOLUME CONTROL IN 1.25dB STEPS
TREBLE AND BASS CONTROL
TWO SPEAKER ATTENUATORS:
- INDEPENDENT SPEAKERS CONTROL
IN 1.25dB STEPS
- INDEPENDENT MUTE FUNCTION
ALL FUNCTIONS PROGRAMMABLE VIA SE-
RIAL I2 C BUS
DESCRIPTIONThe TDA7312 is a volume, tone (bass and treble)
balance (Left/Right) processor for quality audio appli-
cations.
Control is accomplished by serial I2 C bus microproc-
essor 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:SDA, SCL, DIG OUT 1, DIG OUT 2 Pins are high impedance when VS = 0
(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.
