    Hi, Yun,

    Regarding the recommended pull-up resistor for the SDA and SCL lines, let me correct this statement due to a misunderstanding from my side and a typo in the datasheet. The high-level input current (IIH) corresponds for the digital input lines except the I2C lines (this is a typo in the datasheet that we will work to correct it). So, what we recommend is use a minimum of 3.3Kohm resistor as pull-up resistor. This is the value that we use in our EVMs under a 3.3V voltage and it works correctly.

    Regarding the maximum EN, I2C, STANDBY, IN+/- pins voltage, unfortunately we cannot provide details about the internal architecture of each pin, but they share a different circuitry to AVDD that doesn't allow to support more than the voltage specified in the datasheet.

    Please let me know if you have additional questions or comments.

    Best regards,
    Luis Fernando Rodríguez S.
