DIFFERENCE_OF_SQUARES

The AD534 is remarkably easy to use in the implementation of the approximation formulas described in Chapter 2-1 of the NonLinectr Circuits Hctndbook. Many of these involve implicit loops to generate the function and previously required several additional op amps for the addition and subtraction of the various terms. This circuit is an example of what can be done with extemal resistors only. For φ between 00 and 900, the approximation maintains a theoretical accuracy to within 0.5% of fullscale; 0.75% is practical with AD534L and 0.1% resistances were used.
