Mini-Component Audio 1.3 Description
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 28Г—48-bit …
