... 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 AD9631/AD9632 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 ...

... AD9631 and AD9632 the best attributes of both voltage and current feedback amplifiers. Large Signal Performance The outstanding large signal operation of the AD9631 and AD9632 is due to a unique, proprietary design architecture. In order to maintain this level of performance, the maximum 550 V-MHz product must be observed (e.g., @ 100 MHz, V ...

... AD9631/AD9632 Layout Considerations The specified high speed performance of the AD9631 and AD9632 requires careful attention to board layout and component selection. Proper RF design techniques and low-pass parasitic component selection are mandatory. The PCB should have a ground plane covering all unused portions of the component side of the board to provide a low impedance path ...
