EVAL-ADG772
FEATURES
Full-featured evaluation board for ADG772
On-board USB connectors
No external power supply needed
GENERAL DESCRIPTION
This data sheet describes the evaluation board for the ADG772,
which is a low voltage, CMOS device that contains two
independently selectable, single-pole, double-throw (SPDT)
switches. The ADG772 is designed as a general analog-to-
digital switch that can be used for routing both USB 1.1
(12 Mbps) and USB 2.0 (480 Mbps) signals.
Figure 1 shows the EVAL-ADG772 evaluation board. The
ADG772 is soldered onto the evaluation board in a tiny
1.3 mm × 1.6 mm ultra thin LFCSP located in the center of the
board and is designated as U1. The EVAL-ADG772 can be used
without an external power supply; in which case, the USB
supply powers the device.
The evaluation kit contains a fully fitted PCB and a CD that
contains the ADG772 and the EVAL-ADG772 data sheets.
Refer to the ADG772 data sheet for full data on the part.
Consult the ADG772 data sheet in conjunction with this data
sheet when using the evaluation board.
CONNECTING SIGNALS TO THE BOARD
The board is fitted with three USB connectors that allow the
host to switch between two USB devices. All signals applied to
the switch can be monitored using the test points provided on
the board.
