Product Details

The EVAL-ADG7421FEBZ is the evaluation board for the ADG7421F, which features two single-pole/single-throw (SPST) switch channels. The ADG7421F has overvoltage detection and protection circuitry on the source pins and is protected against signals up to −60 V and +60 V in both the powered and unpowered states.

Figure 1 shows the EVAL-ADG7421FEBZ in a typical evaluation setup. The ADG7421F is soldered to the center of the evaluation board, and two wire screw terminals are provided to connect to each of the source and drain pins. Three screw terminals are used to power the device. A fourth terminal is used to provide a user defined digital voltage, to supply the LED, which is mounted to provide visual indication of the fault status of the switch.

Full specifications on the ADG7421F are available in the product data sheet, which must be consulted in conjunction with this user guide when using the evaluation board.
