DAC8571: Determine if I2C communication is established with DAC8571

Todd Anderson

Part Number: DAC8571

All:

We have a requirement to report successful I2C communication.

I just did a write to the temporary register and readback of the value, which would probably satisfy that requirement (without sending a value to the output).

Is there another method that could be used?

Regards,

Todd Anderson

    Hi Todd,

    If you are looking to verify both writing and reading for the device, this is likely the best way.

    The datasheet mentions on page 20:
    "The I2C bus can be noisy and data integrity and can be a problem in a system of many I2C devices. To enable I2C system verification, DAC8571 provides read back capability for the user."

    Thanks,
    Lucas
