    I need help to calculate the offset voltage of HMC1052. It is confused
    from the data sheet. Is offset equal to (max-min)/2 or when you read
    the output voltage during the SET/RESET pulse?

    The datasheet says: "Offset = (OUT+) – (OUT-), Field = 0 gauss after
    Set pulse" and later it says, "Typically a reset pulse is sent first,
    followed by a set pulse a few milliseconds later. By shoving the
    magnetic domains in completely opposite directions, any prior magnetic
    disturbances are likely to be completely erased by the duet of pulses."
    So it appears to be the zero-field output measured _after_ a reset/set.

    Hi Win,

    Thank you for your response to my post. What I am confuse, if in
    overall calculating the arctan(y/x), the Offset = (OUT+) - (OUT-)
    would play any role or not. I've read several posting and seen mostly
    the x and mainly related to Xoff , Yoff, Xmax,Ymax, Xmin, Ymin, Xsf and
    Ysf are related to the arctan(y/x).

    High regards,
