Detailed description:
1: PCB adopts double-layer immersion gold process design to ensure good passing performance of large and small currents
2: High quality active crystal oscillator
3: Have their own development program, complete chip optimization, better signal integrity, less signal distortion
4: Dual op amps are used, and the op amps are powered by positive and negative power supplies.
5: The MCLK of the ES9038Q2M is an independent clock of 100M, so you only need to input DATA BCK LRCK.
6: Power adapter voltage conversion chip LT1763 is a micro power, low noise, low dropout regulator. Capable of delivering 500mA of output current and a differential voltage of 300mV
