Overview
The ADG2188BCPZ-REEL7, produced by Analog Devices Inc., is an analog crosspoint switch with an array size of 8 × 8. This device features a bidirectional switch array, allowing the rows and columns to be configured as either inputs or outputs. The switch array consists of 64 switch channels, which can be addressed and configured through an I2C-compatible interface. The device supports standard, full speed, and high speed (3.4 MHz) I2C interfaces. It is packaged in a 32-lead, 5 mm × 5 mm LFCSP_WQ (Lead Frame Chip Scale Package with exposed pad).
