... 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 AD8582 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 ...

... X X ^Denotes positive edge triggered. OPERATION The AD8582 is a complete, ready-to-use dual 12-bit digital-to- analog converter. Only one +5 V power supply is necessary for operation. It contains two voltage-switched, 12-bit, laser- trimmed digital-to-analog converters, a curvature-corrected bandgap reference, rail-to-rail output op amps, input registers, and DAC registers. The parallel data interface consists of twelve data bits, DB0– ...
