The AD633-EVALZ was tested for division.
The same voltage signal was applied to the denominator and the numerator using a function generator.
The denominator and the numerator are 1V sin signal and offset volatage is 1V, frequency is 80Hz.
Negative supply voltage is -10V and Positive supply voltage is 10V.
According to the manual, the output voltage signal is -10V.*(NUM/DENOM). so I think -10V should come out.
However, the output signal changes according to the negative supply voltage.
When I apply the negative supply voltage -9V, the output voltage signal is -9V.
And when I apply the negative supply voltage -15V, the output voltage signal is -15V.
The output voltage signal is not changed by positive supply voltage.
Can you tell me why?
