GENERAL DESCRIPTION
The EVAL-ADGS1208SDZ/EVAL-ADGS1209SDZ are the
evaluation boards for the
. The
are low on capacitance (C
ON
), low
charge injection (Q
INJ
), 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
devices together to enable the
configuration of multiple devices with a minimal amount of digital
lines. The
also support burst mode, which
decreases the time between SPI commands.
Figure 1 shows the EVAL-ADGS1208SDZ/EVAL-ADGS1209SDZ
typical evaluation board setup. The EVAL-ADGS1208SDZ/
EVAL-ADGS1209SDZ are controlled by the
system demonstration platform (SDP), which connects to a PC
via a USB port. The
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.

The evaluation board interfaces to the USB port of a PC via the
SDP board. The
