The EVAL-ADGS1412SDZ is the evaluation board for the ADGS1412. The ADGS1412 is an iCMOS, quad single-pole, single-throw (SPST) switch controlled by a serial peripheral interface (SPI). The SPI has robust error detection features. These are cyclic redundancy check (CRC) error detection, invalid read/write address detection and serial clock (SCLK) count error detection. It is possible to daisy-chain multiple ADGS1412 devices together. This enables the configuration of multiple devices with a minimal amount of digital lines. The ADGS1412 also supports burst mode that decreases the time between SPI commands.
The EVAL-ADGS1412SDZ is controlled by the SDP which connects to a PC via USB. The ADGS1412 is on the center of the evaluation board, and wire screw terminals are provided to connect to each of the source and drain pins. Three screw terminals power the device and a fourth terminal provides users defined digital logic supply voltage, if required. Alternatively, the digital logic supply voltage can be supplied from the SDP.
Full specifications on the ADGS1412 are available in the ADGS1412 data sheet available from Analog Devices and should be consulted in conjunction with user guide UG-1067 when using the evaluation board.
The evaluation board interfaces to the USB port of a PC via the SDP board. The EVAL-SDP-CB1Z board (SDP-B controller board) is available to order on the Analog Devices website at www.analog.com.
