AD633-EVALZ

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?

Thanks!
