    Hello Kien,

    Please find my comments below:

    • Power Supply decoupling looks good. 
    • i see series resistors on the digital interface pins. This is good as it will help with ringing and overshoot.
    • I2C lines should be pulled up to IOVDD. I assume this is happening on another schematic page as I do not see anything here. 
    • The 1kohm resistors at the output concern me. They will limit the output power. it is recommended using ferrite beads

    Regards,
