GENERAL DESCRIPTION
The ADG2108 is an analog cross point switch with an
array size of 8 × 10. The switch array is arranged so that
there are eight columns by 10 rows, for a total of 80 switch
channels. The array is bidirectional, and the rows and columns
can be configured as either inputs or outputs. Each of the 80
switches can be addressed and configured through the I2C-
compatible interface. Standard, full speed, and high speed
(3.4 MHz) I2C interfaces are supported. Any simultaneous
switch combination is allowed. An additional feature of the
ADG2108 is that switches can be updated simultaneously,
using the LDSW command. In addition, a RESET option
allows all of the switch channels to be reset/off. At power on,
all switches are in the off condition. The device is packaged
in a 32-lead, 5 mm × 5 mm LFCSP_WQ.
