TDA7343 Datasheet - ST Microelectronics

TDA7343 DIGITALLY CONTROLLED AUDIO PROCESSOR

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 DIP28 SO28 ORDERING NUMBER: TDA7343 (DIP28) TDA7343D (SO28) CMOS-switching techniques .

® 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 INCLUDING 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 FU.

TDA7343 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.
