1 / 14 page  TDA7343 DIGITALLY CONTROLLED AUDIO PROCESSOR INPUT MULTIPLEXER - TWO STEREO AND ONE MONO INPUTS - SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTATION TO DIFFERENT SOURCES FULLY PROGRAMMABLE LOUDNESS FUNCTION VOLUME CONTROL IN 0.3dB STEPS IN- CLUDING GAIN UP TO 20dB ZERO CROSSING MUTE AND DIRECT MUTE SOFT MUTE CONTROLLED BY SOFTWARE OR HARDWARE PIN BASS AND TREBLE CONTROL FOUR SPEAKER ATTENUATORS - FOUR INDEPENDENT SPEAKERS CONTROL IN 1.25dB STEPS FOR BALANCE AND FADER FACILITIES - INDEPENDENT MUTE FUNCTION ALL FUNCTIONS PROGRAMMABLE VIA SE- RIAL I 2 CBUS DESCRIPTION The TDA7343 is an upgrade of the TDA7313 audioprocessor. Thanks to the used BIPOLAR/CMOS technology, very low distortion, low noise and DC-stepping are obtained. Due to a highly linear signal processing, using CMOS-switching techniques instead of standard bipolar multipliers, very low distortion and very low noise are obtained Several new features like softmute, zero-crossing mute and pause detector are implemented. The Soft Mute function can be activated in two ways: 1 Via serial bus (bit D0, Mute Byte) 2 Directly on pin 22 through an I/O line of the microcontroller Very low DC stepping is obtained by use of a BICMOS technology. November 1999 ® ORDERING NUMBER: TDA7343 (DIP28) TDA7343D (SO28) DIP28 SO28 1/14 |
