ES9038Q2M ES9038 I2S Input Decoder board mill board DAC IIS-32bit 192K /DSD64 128 256  The board is a finished board, and the welding is guaranteed for 1 year. The analysis power, the details, and the dynamic level are improved compared with the previous generation. DSD support is very good, very suitable for grinding machine use, the board has added a soft control CPU to automatically optimize the ES9038 kernel The board is gold-plated on both sides 1 I2S line included with the board Main selling points: 1: Perfect and seamless use with the interface, PCM DSD switching without defects.  2: Two-channel AC power supply, the operational amplifier works in high voltage and large dynamic range, low-noise LDO professional regulated power supply LT1963, multi-line linear power supply regulated.  3: ES9028Q2M parameters are relatively complete, 129dB DNR -120dB THD+N is not comparable to the old chip.  5: Support IIS-32bit 192K /DSD64 128 256 Board power supply: AC 15-18VX2 (3 wires) + AC 7-12V (2 wires) Output terminal: RCA+3.5 terminal, can be directly connected to power amplifier, headphone amplifier, or earphone directly The main capacitors are ELNA AUDIO gold capacitors, ELNA brown god capacitors, etc. The op amp is a double-precision 5532DD regulator and a low-noise BB-TI LTV1117.LT1963 high-end regulator. The earphone terminal is fully shielded by Foxconn, and the RCA is a Taiwanese gold-plated terminal, which is better than the US CMC816 PCB size: 91X98MM
