GENERAL DESCRIPTION
The TDA1546T is the first Bitstream Continuous Calibration digital-to-analog converter (BCC-DAC) to feature unique signal processing functions. In addition to the basic functions of digital filtering and digital-to-analog conversion, it offers such advanced digital signal processing functions as volume control, tone control, bass boost, peak or spectrum analyzer readout and many more convenient functions. The digital processing features are of high sound quality due to the wide dynamic range of the bitstream conversion technique.
