Instrumentation applications GUARANTEED PERFORMANCE OVER Available in chip form TEMPERATURE GENERAL DESCRIPTION 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 25C, and multiplier/divider. It guarantees a maximum multiplying error are rated for operation from 0C to 70C. 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 25C 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 55C and +125C. 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 ADVANTAGES OF ON THE CHIP TRIMMING OF trim networks. 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 10V Z . In addition to these basic techniques can be used rather than more complex hybrid approaches. functions, the differential X and Y inputs provide significant 4. High impedance X and Y inputs with negligible circuit operating flexibility both for algebraic computation and transducer loading. instrumentation applications. Transfer functions, such as XY/10 V, 2 2 2 5. Differential X and Y inputs for noise rejection and additional (X Y )/10 V, X /10 V, and 10 V Z/(X X ), are easily attained 1 2 computational flexibility. and are extremely useful in many modulation and function 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.
