com I2C® CMOS 8 × 8 Unbuffered Analog Switch Array with Dual/Single Supplies ADG2188 FEATURES I2C-compatible interface 3.
4 MHz high speed I2C option 32-lead LFCSP_VQ (5 mm × 5 mm) Double-buffered input logic Simultaneous update of multiple switches Up to 300 MHz bandwidth Fully specified at dual ±5 V/single +12 V operation On resistance 35 Ω maximum Low quiescent current < 20 μA GENERAL DESCRIPTION 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_VQ.
