I am trying to do on-board division with the AD538 chip. I have to voltage inputs which can have either negative or positive polarity. The discussed cases in the data sheet are clear for when the voltages are positive only.Since the transfer function is Vy(Vz/Vx), I would use a reference signal for Vz and use it with the m=1 case. Any help with my specific case in terms of the wiring would be appreciated.
Thanks.
