Description

The audioprocessor TDA7437N is an upgrade of the TDA731X audioprocessor family.

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 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 Very low DC stepping is obtained by use of a BICMOS technology.

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

■ Four speaker attenuators- four independent

speakers control in 1dB steps for balance and fader facilities

■ Pause detector programmable threshold

■ All functions programmable via serial I2C bus
