FEATURES
Multiple connection options Support for active probes Provisions for cable terminations Support for printed circuit board (PCB) edge mounted coaxial connectors Easy configuration SUPPORTED iCoupler DEVICES Sample iCoupler digital isolators must be ordered separately; supported iCoupler devices are as follows: ADuM110N ADuM120N/ADuM121N ADuM210N ADuM225N/ADuM226N ADuM7240/ADuM7241 ADuM1200/ADuM1201 ADuM1210 ADuM3200/ADuM3201 ADuM3210/ADuM3211 ADuM1280/ADuM1281 GENERAL DESCRIPTION The EV AL-1CH2CHSOICEBZ supports single- and dual-channel iCoupler® standard data isolators in 8-lead SOIC packages. The evaluation board provides a JEDEC standard, 8-lead SOIC_N and 8-lead SOIC_W pad layout. This layout supports signal distribution, loopback, and loads referenced to the VDDx or GNDx planes, as well as optimal bypass capacitance. Signal sources can be conducted to the board through header pins or through edge mounted SMA connectors (SMA connectors must be ordered separately). Screw terminal blocks on the board provide power connections. The board includes 0.2 inch header positions for compatibility with active probes (probe header pins must be ordered separately). The evaluation board follows best PCB design practices for 4-layer boards, including a full power and ground plane on each side of the isolation barrier. No other electromagnetic interference (EMI) or noise mitigation design features are included on this board. In cases of high speed operation, or when ultralow emissions are required, refer to the AN-1109 Application Note for additional board layout techniques.
