It guarantees a maximum multiplying error of ±1.0% and a ±10 V output voltage without the need for any external trimming resistors or output op amp. Because the AD532 is internally trimmed, its simplicity of use provides design engineers with an attractive alternative to modular multi- pliers, and its monolithic construction provides significant ad- vantages in size, reliability and economy. Further, the AD532 can be used as a direct replacement for other IC multipliers that require external trim networks (such as the AD530). FLEXIBILITY OF OPERATION The AD532 multiplies in four quadrants with a transfer func- tion of (X1 – X2)(Y1 – Y2)/10 V, divides in two quadrants with a 10 V Z/(X1 – X2) transfer function, and square roots in one quadrant with a transfer function of ±√10VZ. In addition to these basic functions, the differential X and Y inputs provide significant operating flexibility both for algebraic computation and transducer instrumentation applications. Transfer functions, such as XY/10 V, (X 2 – Y2)/10 V, ±X2/10 V and 10 V Z/(X 1 – X2), are easily attained 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 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. GUARANTEED PERFORMANCE OVER TEMPERATURE The AD532J and AD532K are specified for maximum multi- plying errors of ±2% and ±1% of full scale, respectively at +25 °C, and are rated for operation from 0°C to +70°C. The AD532S has a maximum multiplying error of ±1% of full scale at +25 °C; it is also 100% tested to guarantee a maximum error of ±4% at the extended operating temperature limits of –55°C and +125 °C. All devices are available in either the hermetically- sealed TO-100 metal can, TO-116 ceramic DIP or LCC packages. J, K and S grade chips are also available. ADVANTAGES OF ON-THE-CHIP TRIMMING OF THE MONOLITHIC AD532 1. True ratiometric trim for improved power supply rejection. 2. Reduced power requirements since no networks across sup- plies are required. 3. More reliable since standard monolithic assembly techniques can be used rather than more complex hybrid approaches. 4. High impedance X and Y inputs with negligible circuit loading. 5. Differential X and Y inputs for noise rejection and additional computational flexibility. REV. B One Technology Way, P.O.
