The TAS3202 is an audio system-on-a-chip (SOC) designed for mini/micro systems, multimedia-speaker, and MP3 player docking systems. 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
