RE-EXAMINATION OF MULTIPLIER/DIVIDER ACCURACY Traditionally, the “accuracy” (actually the errors) of analog multipliers and dividers have been specified in terms of percent of full scale. Thus specified multiplier error with full-scale output would mean a ...

... Model AD538AD AD538BD AD538ACHIPS AD538SD AD538SD/883B CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD538 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

ANALOG COMPUTATION OF POWERS AND ROOTS It is often necessary to raise the quotient of two input signals to a power or take a root. This could be squaring, cubing, square- rooting or exponentiation to some noninteger power. Examples include ...

AD538 TRANSDUCER LINEARIZATION Many electronic transducers used in scientific, commercial or industrial equipment monitor the physical properties of a device and/or its environment. Sensing (and perhaps compensating for) changes in pressure, temperature, moisture or other physical phenomenon can be an ...
