TDA7342EQ2N

Digitally controlled audio processor

Features

■ Input multiplexer

– Two stereo and one mono inputs

– One quasi differential input

– Selectable input gain for optimal adaptation

to different sources

■ Fully programmable loudness function

TQFP32

■ Volume control in 0.3dB steps including gain

up to 20dB

■ Zero crossing mute, soft mute and direct mute

■ Bass and treble control

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, and zero-crossing mute are

■ Four speaker attenuators

– Four independent speakers control in

1.25dB steps for balance and fader facilities

– Independent mute function

■ All functions programmable via serial I²C bus

implemented. The soft Mute function can be

activated in two ways:

1. Via serial bus (Mute byte, bit D0)

Description

2. Directly on pin 21 through an I/O line of the

microcontroller

The audioprocessor TDA7342EQ2N is an

upgrade of the TDA731X audioprocessor family.

Very low DC stepping is obtained by use of a

BICMOS technology.
