GENERAL DESCRIPTION
This user guide describes the evaluation board for the ADG2188
I
2
C CMOS 8 × 8 analog switch array with dual/single supplies.
The array is bidirectional, and, as a result, the rows and columns
can configure as either inputs or outputs. Any number of
combinations can be active at one time.
The ADG2188 has a maximum difference of 15 V between the
V
DD
and V
SS
inputs. Therefore, take care to not to exceed the
maximum of 15 V difference when connecting the power supplies.
The evaluation board interfaces to the USB port of a PC. The
evaluation software is available with the evaluation board that
allows the user to easily program the ADG2188. The E VA L -
ADG2188EBZ can also be used as a standalone board.
Complete specifications for the ADG2188 are available in the
ADG2188 data sheet available from Analog Devices, Inc., and
should be consulted in conjunction with this data sheet when
using the evaluation board.
