DAC43701: Schematic Review

Part Number: DAC43701
Other Parts Discussed in Thread: TLV3601,

Hi experts,

Would you please support to review the schematic of DAC43701? It's used to output adjustable Vref for comparator TLV3601 for core power(0.65/0.75/0.85V) monitoring.

    Hi Allan,

    The schematic shows the DAC43701 OUT pin (pin 8) directly tied to the TLV3601 OUT pin (pin 1). To use the DAC43701 as a VREF source, it should be connected to one of the TLV3601 comparator inputs to serve as the reference threshold.

    Let me know if I am misunderstanding the setup. Right now, it seems like there would be some contention between the DAC output and comparator output.

    Regards,

    James
