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_VQ.
