It includes analog interface functions: two multiplex (MUX) stereo inputs with one stereo analog-to-digital converter (ADC) and one stereo digital-to-analog converter (DAC) with analog outputs consisting of differential stereo line drivers. Four channels of serial digital audio processing are also provided. The TAS3202 has a programmable audio digital signal processor (DSP) that preserves high-quality audio by using a 48-bit data path, 28-bit filter coefficients, and a single-cycle 28×48-bit multiplier. The programmability feature allows users to customize features in the DSP RAM. The TAS3202 is composed of eight functional blocks: 1. Analog input/mux/stereo ADC 2. Stereo DAC 3. Analog reference system 4. Power supply 5. Clocks, digital PLL, and serial data interface 6. I2C control interface 7. 8051 microcontroller 8. Audio DSP – digital audio processing 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
