The AR37T01 is a digitally coded stereo PCM-to-PDM conversion IP with 8-bit pattern-code programming.
The IP translates parallel PCM input data into single-bit digital switching pulse-density modulated (PDM) output. The IP converts stereo audio data through ∑∆ modulator and filters. The 1-bit PDM output can drive off-chip stand-alone PDM-type amplifier with high power-efficiency.
The IP is portable to any logic process node for silicon realization. It is now silicon-proven in TSMC16nm and 28nm logic processes.
