Overview
The ADG2128BCPZ-REEL7 is an analog crosspoint switch produced by Analog Devices Inc. This device features an 8 x 12 switch array, providing a total of 96 switch channels. The switch array is bidirectional, allowing the rows and columns to be configured as either inputs or outputs. The ADG2128 is controlled through an I2C-compatible interface, supporting standard, full speed, and high speed (3.4 MHz) I2C interfaces. This component is packaged in a 32-lead, 5 mm x 5 mm LFCSP (Lead Frame Chip Scale Package) and is fully specified for operation over a temperature range of -40°C to +85°C.
