TDA7343 - DIGITALLY CONTROLLED AUDIO PROCESSOR

Datasheet Summary

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.

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 1/14 CSM 2/14 C8 2.2µF C15 100nF 4 SPKR ATT 26 MUTE LOUD+ VOL BASS SPKR ATT 24 MUTE 28 SOFT MUTE SERIAL BUS.
