DAC8565 Detect SPI communation Error

Baris Goksu

Part Number: DAC8565
Other Parts Discussed in Thread: DAC80504

The output voltage can be measured to see if there are any write errors. But my wish is to make sure that the protocol is successful without checking the output voltages.
For example, DAC8565 was damaged in time, and I could no longer write anything to the register of the DAC8565 using the SPI Interface.
Can I understand the situation that I sampled in any way without measuring the output voltages?

    Baris,

    DAC8565 does not feature any SDO pin for the SPI interface which would enable any read-back functionality. Nor does it include any ALARM or FAULT functionality which would allow you to detect any specific failure mode.

    DAC80504 is a more modern device, which includes more of the capabilities that you are likely interested in. This includes the capability of SPI read-back via an SDO pin as well as CRC frame-error checking to ensure the integrity of the SPI read and write transactions.
