The EVAL-ADGS1208SDZ/EVAL-ADGS1209SDZ are the evaluation boards for the ADGS1208/ADGS1209. The ADGS1208/ADGS1209 are low on capacitance (CON), low charge injection (QINJ), 8:1/dual 4:1 multiplexers controlled by a serial peripheral interface (SPI). The SPI has robust error detection features, including 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 ADGS1208/ADGS1209 devices together to enable the configuration of multiple devices with a minimal amount of digital lines. The ADGS1208/ADGS1209 also support burst mode, which decreases the time between SPI commands.
The EVAL-ADGS1208SDZ/ EVAL-ADGS1209SDZ are controlled by the EVAL-SDP-CB1Z system demonstration platform (SDP), which connects to a PC via a USB port. The ADGS1208 or ADGS1209 is on the center of the evaluation board, and wire screw terminals are provided to connect to each source and drain pin. Three screw terminals power the device and, if required, a fourth terminal provides users with a defined digital logic supply voltage. Alternatively, the digital logic supply voltage can be supplied from the SDP.
Consult the ADGS1208/ADGS1209 data sheet (available from Analog Devices, Inc.) in conjunction with User Guide UG-1271. 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 for order at www.analog.com/SDP-B.
