The ADG2128BCPZ-HS-RL7 is an Analog Devices I2C CMOS 8 x 12 analog crosspoint switch array featuring 96 bidirectional switch channels. The array is arranged in 8 columns by 12 rows, where rows and columns can be configured as either inputs or outputs. Each switch is addressed and configured through an I2C-compatible interface supporting standard (100 kHz), full-speed (400 kHz), and high-speed (3.4 MHz) modes. The LDSW command enables simultaneous update of multiple switches. A RESET option resets all switch channels. The device operates from dual ±5V or single +12V supplies and is packaged in a 32-lead 5mm x 5mm LFCSP.

The ADG2128 operates as an analog crosspoint switch with three subsystems: (1) The I2C interface logic receives serial commands (SDA/SCL) to address and configure individual switches within the 8×12 array. Double-buffered input logic ensures glitch-free switching. (2) The switch array consists of 96 CMOS transmission gates connecting any of the 12 row lines (X0-X11) to any of the 8 column lines (Y0-Y7). Each switch has an on-resistance of 35 Ω max and supports bidirectional signal flow. (3) The LDSW command allows loading new switch configurations into a shadow register and then applying all changes simultaneously, preventing intermediate states. The RESET pin clears all switch states to off.
