DESCRIPTION

The audioprocessor TDA7437 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.

■ 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 BALANCEAND FADER FACILITIES

■ PAUSE DETECTOR PROGRAMMABLE THRESHOLD

■ ALL FUNCTIONS PROGRAMMABLE VIA SERIAL I2 CBUS
