Hello team,

My customer has a question about TLV320DAC32 reset.

1) Is the wait time required from  reset released to I2C communication start?

2) If wait time is needed. how long do the wait time need?

Your support would be so appreciated.

Best Regards,

    Hello, Tamazaki-san,

    Yes, a wait time is required when the RESET pin is pulled down and pulled up.

    In order to perform a correct RESET sequence, the RESET pin must be pulled low for at least 10ns. Then, after the RESET pin is pulled high, the user should wait for at least 1ms to start the I2C communication. Otherwise, it may result in an incorrect RESET sequence and it may affect the registers values.

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

    Best regards,
    Luis Fernando Rodríguez S.
