The ADG2188 is an analog cross point switch with an array size of 8 × 8. The switch array is arranged so that there are eight columns by eight rows, for a total of 64 switch channels. The array is bidirectional, and the rows and columns can be configured as either inputs or outputs. Each of the 64 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 ADG2188 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.

Evaluation Kits (1)
This user guide describes the evaluation board for the ADG2188 I2C 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 VDD and VSS 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 EVAL-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.
