ADG2188

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

2

the I

C-compatible interface. Standard, full speed, and high speed (3.4 MHz) I simultaneous switch combination is allowed. An additional feature of the ADG2188 is that switches can be updated simultaneously, using the LDSW command. In addition,

RESET

a

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.

C interfaces are supported. Any

This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
