GENERAL DESCRIPTION
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.
Figure 1 shows the EVAL-ADGS1412SDZ in a typical evaluation
setup. The EVAL-ADGS1412SDZ is controlled by the SDP which
connects to a PC via a USB port. 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 with a
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, Inc., and
should be consulted in conjunction with this user guide 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.
