1 Introduction

NanoHat PCM5102A

• The Matrix - NanoHat PCM5102A module uses TI's DAC audio chip PCM5102A and NS' low-noise, ultra-low dropout LP2992 regulator. PCM5102A's sample rates up to 384kHz and its resolution is 32-bit.
• Its dynamic range is 112dB. Its THD+N at –1 dBFS is -93db. Its full-scale single-ended output is 2.1V. The SNR is 120dB.
• Its onboard VS1838B infrared receiver allows it to be remote-controlled.
• This module has exactly the same dimension as the NanoPi NEO/Air and can be stacked on an NanoPi NEO/Air.
