1 Introduction
- 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.
- The SNR is 120dB.
模块信噪比112db,失真-93db,可直接输出2.1V RMS音频电压。模块软斜升或斜降搭配模拟静音,可实现120dB 静音信噪比(SNR)。
- Its onboard VS1838B infrared receiver allows it to be remote-controlled.
- NanoHat PCM5102A和NanoPi NEO/Air的外形尺寸和接口完全相同,可直接堆叠在NanoPi NEO或Air上。
2 特性
- 超低带外噪声
- 可接收 16、 24 和 32 位音频数据
- PCM 数据样式: I2S, 左对齐
- 采样率为384kHz,分辨率为32-Bit
- 板载红外接收。
