AD734AQ (ANALOG DEVICES)

The AD734AQ is a quadrant high-performance Analogue Multiplier/Divider is pin compatible with the industry-standard AD534 and provides the transfer function W=XY/U. The AD734 provides a low impedance voltage output with a full power (20Vp-p) bandwidth of 10MHz. Total static error (scaling, offsets and nonlinearities combined) is 0.1% of full scale. Distortion is typically less than -80dBc and guaranteed. The low capacitance X, Y and Z inputs are fully differential. In most applications, no external components are required to define the function. The internal scaling (denominator) voltage, U, is 10V, derived from a buried-Zener voltage reference. A new feature provides the option of substituting an external denominator voltage, allowing the use of the AD734 as a two-quadrant divider with a 1000:1 denominator range and a signal bandwidth that remains.
