TDA7319
3 BAND DIGITAL CONTROLLED AUDIO PROCESSOR
ONE STEREO INPUT
ONE STEREO OUTPUT
TWO INDEPENDENT VOLUME CONTROL IN
1.0dB STEPS
TREBLE, MIDDLE AND BASS CONTROL IN
1.0dB STEPS
ALL FUNCTIONS PROGRAMMABLE VIA SE-
RIAL I2 CBUS
DESCRIPTION
The TDA7319 is a volume and tone (bass , mid-
dle and treble) processor for quality audio appli-
cation in car radio and Hi-Fi system.
Control is accomplished by serial I2C bus micro-
processor interface.
The AC signal setting is obtained by resistor net-
works and switches combined with operational
amplifiers.
DIP20
SO20
ORDERING NUMBERS: TDA7319 (DIP20)
TDA7319D (SO20)
Thanks to the used BIPOLAR/MOS Technology,
Low Distortion, Low Noise and Low Dc stepping
are obtained.
