Would the MAX5705 internal reference work when the external reference is connected and even when it's configured to use internal reference of 2.048 V and when the REF pin is not driven (i.e., REF command byte setting is 0b00100010 or 0b00100110)?
Answer:
No, when an external voltage is connected between REF, the MAX5705 powers up and resets to external reference mode.
