TDA7437N

Digitally controlled audio processor

Features

■ Input multiplexer

– Four stereo, one mono input, and one

differential input

– Selectable input gain for optimal adaptation

to different sources

■ Fully programmable loudness function

■ Volume control in 1dB steps including gain up

to 16dB

■ Zero crossing mute, soft mute and direct mute

■ Bass and treble control

LQFP44

■ Four speaker attenuators- four independent

speakers control in 1dB steps for balance and

fader facilities

■ Pause detector programmable threshold

low noise are obtained. Several new features like

softmute, and zero-crossing mute are

■ All functions programmable via serial I C bus

implemented. The soft Mute function can be

activated in two ways either via the serial bus

(Mute byte, bit D0), or directly on pin 28 through

an I/O line of the microcontroller

Description

The audioprocessor TDA7437N is an upgrade of

the TDA731X audioprocessor family.

Very low DC stepping is obtained by use of a

BICMOS technology.

Due to a highly linear signal processing, using

CMOS-switching techniques instead of standard

bipolar multipliers, very low distortion and very

Order codes
