ADG2128:  I2C CMOS 8 X 12 Analog Switch Array with Dual/Single Supplies

Product Description

The ADG2128 is an analog crosspoint switch with an array size of 8 x 12. The switch array is arranged such that there are 8 columns by 12 rows, in total 96 switch channels. The array is bidirectional, so the rows and columns may be configured as either inputs or outputs. Each of the 96 switches may be addressed and configured through the I2C compatible interface. Any number or combinations may be activate at any one time. A futher feature of the ADG2128 is that a number of switches can be updated simultaneously using the LDSW command. Also, a RESET option allows all of the switch channels to be reset/off. On power on, all switches will be in the OFF condition. The device is packaged in a 32-lead LFCSP packages.
