SQUARE ROOT
The connections for square root mode are shown in Figure 18.
Similar to the divide mode, the multiplier cell is connected in
the feedback of the op amp by connecting the output back to
both the X and Y inputs. The diode D

DIFFERENCE OF SQUARES
The differential input capability of the AD532 allows for the
algebraic solution of several interesting functions, such as the
difference of squares, X
AD532 is configured in the square mode, with a simple unity
gain inverter connected between one of the signal inputs (Y)
and one of the inverting input terminals (−Y
The inverter should use precision (0.1%) resistors or be otherwise
trimmed for unity gain for best accuracy.
