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

compatible interface. Standard, full speed, and high speed

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_VQ.
