The AD532J and AD532K are specified for maximum multiplying The AD532 is the first pretrimmed, single chip, monolithic errors of ±2% and ±1% of full scale, respectively at 25°C, and multiplier/divider. It guarantees a maximum multiplying error are rated for operation from 0°C to 70°C. The AD532S has a of ±1.0% and a ±10 V output voltage without the need for any maximum multiplying error of ±1% of full scale at 25°C; it is external trimming resistors or output op amp. Because the AD532 also 100% tested to guarantee a maximum error of ±4% at the is internally trimmed, its simplicity of use provides design extended operating temperature limits of −55°C and +125°C. engineers with an attractive alternative to modular multipliers, All devices are available in either a hermetically sealed TO-100 and its monolithic construction provides significant advantages metal can or 14-lead D-14 side brazed ceramic DIP. The J, K, in size, reliability, and economy. Further, the AD532 can be a and S grade chips are also available. direct replacement for other IC multipliers that require external

THE MONOLITHIC AD532 FLEXIBILITY OF OPERATION
1. True ratiometric trim for improved power supply rejection. The AD532 multiplies in four quadrants with a transfer function of 2. Reduced power requirements since no networks across (X1 − X2)(Y1 − Y2)/10 V, divides in two quadrants with a 10 V Z/ supplies are required. (X1 − X2) transfer function, and square roots in one quadrant 3. More reliable because standard monolithic assembly with a transfer function of  10 V Z . In addition to these basic techniques can be used rather than more complex hybrid functions, the differential X and Y inputs provide significant approaches. operating flexibility both for algebraic computation and transducer 4. High impedance X and Y inputs with negligible circuit instrumentation applications. Transfer functions, such as XY/10 V, loading. (X2 − Y2)/10 V, ±X2/10 V, and 10 V Z/(X 5. Differential X and Y inputs for noise rejection and additional 1 − X2), are easily attained and are extremely useful in many modulation and function computational flexibility. generation applications, as well as in trigonometric calculations for airborne navigation and guidance applications, where the monolithic construction and small size of the AD532 offer considerable system advantages. In addition, the high common- mode rejection ratio (CMRR) (75 dB) of the differential inputs makes the AD532 especially well qualified for instrumentation applications, as it can provide an output signal that is the product of two transducer generated input signals.
