... SFDR. The AD8018 is available with flexible standby and shutdown modes. Two digital logic bits (PWDN1 and PWDN0) may be used to put the AD8018 into one of three modes: full power, standby (outputs low impedance), and shutdown (outputs high impedance). ...

... 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 AD8018 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 ...

... V of either power supply, and maintaining low distortion. A differential line driver using the AD8018 can provide CPE performance on a single 5 V supply. This performance is enabled by Analog Device’s XFCB process and a novel, two- stage current feedback architecture featuring a patent-pending rail-to-rail output stage ...
