TDA7342 - DIGITALLY CONTROLLED AUDIO PROCESSOR

Datasheet Summary

Description

The audioprocessor TDA7342 is an upgrade of the TDA731X audioprocessor family.

bipolar multipliers, very low distortion and very low noise are obtained.

Features

  • like softmute, and zero-crossing mute are implemented. The soft Mute function can be activated in two ways: 1 Via serial bus (Mute byte, bit D0) 2 Directly on pin 21 through an I/O line of the microcontroller Very low DC stepping is obtained by use of a BICMOS technology. November 1999 1/14 OUT(L) BIN(L) TREBLE(L) SPKR ATT 25 MUTE ZERO CROSS + MUTE LOUD+ VOL BASS SPKR ATT 23 MUTE 28 SOFT MUTE SERIAL BUS.
