HI this is my sch of ad5520. the pin 64(CLL) vee_3v3 is -3.3V and pin 63(CLH) vcc_3v3 is +3.3v.
I change the pin 26(FIN) voltage , the pin 58 (MEASOUT) should from -3.3V to + 3.3V . but the pin 58 (MEASOUT) is -0.256V to 3.3V.
the R74 is 100K. and in force current mode
why the pin 58 (MEASOUT) is -0.256V to 3.3V.
I moved this query to this community. Someone here should be able to help you.
Unfortunately, I cannot address your problem if I dont have a more complete detail on your schematic.
I am looking into this already. Answering the questions above can resolve the issue more quickly.
