A problem about AD5535B voltage output

王思豪 on Nov 20, 2019

I Connect the 60 V power supply to EVAL-AD5535BSDZ's VPP and connect the 5 V supply to AVCC, DVCC, and V+ (5 V). But the measured value of VOUT is not the calculated value based formula of datasheet of AD5535B. The formula is.

Hi,

Kindly describe the inaccuracy you observed, at what output scale do you observe the problem?

What is the voltage applied to REF_IN pin?

With VPP=60V, the maximum REF_IN should be less than 1.18V.

Cheers,

Ivan
