TDA7437 - DIGITALLY CONTROLLED AUDIO PROCESSOR

Description

The audioprocessor TDA7437 is an upgrade of the TDA731X audioprocessor family.

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 35 34 TREB_R IN_R MUXOUT_R LOUD_R DIFFGND_R DIFF_R STEREO4_R STEREO1_R STEREO2_R STEREO3_R MONO 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 DIFFGND_L STEREO4_L STEREO1_L STEREO2_L STEREO.
