Optional: analog division

To obtain division, connect the multiplier output to the $Y_2$ input. Now $Z_1$ is no longer connected to the output, and $Z_2$ is no longer grounded. In this configuration:

$$\mbox{$V_{\rm out}$}= 10 \times \frac{V(Z_2)-V(Z_1)}{V(X_1)-V(X_2)} + V(Y_1)$$

Measure $V_{\rm out}$ for several values of $V(Z_2)-V(Z_1)$ and $V(X_1)-V(X_2)$. For simplicity, you may want to ground $Z_1$, $X_2$, and $Y_1$. Make sure you keep $V(X_1)-V(X_2)$ positive (see the spec sheets of AD534).

The output limits of AD534 are $\pm 11$V. Calculate and plot the minimum value for $V(X_1)-V(X_2)$ as a function of $V(Z_2)-V(Z_1)$ over the $V(Z)$ range of $\pm 10$V.
