TDA7437 DIGITALLY CONTROLLED AUDIO PROCESSOR

The audioprocessor TDA7437 is an upgrade of the TDA731X audioprocessor family. PIN CONNECTION PQFP44 and TQFP44 ORDERING NUMBERS: TDA7437 (PQFP44) TDA7437T (TQFP44) Due to a highly linear signal processing, using CMOS-switching techniques instead of standard bipolar multipliers, very low distortio.

® TDA7437 DIGITALLY CONTROLLED AUDIO PROCESSOR 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 A.

TDA7437 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 28 through an I/O line of the microcontroller Very low DC stepping is obtained by use of a BICMOS technology. 44 43 42 41 40 39 38 37 36
