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 input or output. This product features an I2C-compatible interface, supports a high-speed I2C option of up to 3.4 MHz, has double-buffered input logic for simultaneous update of multiple switches, operates at dual ±5 V/single +12 V, has a maximum on resistance of 35 Ω, and low quiescent current consumption of less than 20 μA.
The ADG2188 analog cross‑point switch provides an 8 × 8 matrix of bidirectional channels, each configurable as input or output. It supports standard, full‑speed and high‑speed (3.4 MHz) I²C interfaces, allowing simultaneous updates of multiple switches.
The device is offered in a 32‑lead LFCSP_VQ package (5 mm × 5 mm) and is available in B‑version (‑40 °C to +85 °C) and Y‑version (‑40 °C to +125 °C) temperature ranges. Detailed specifications, timing diagrams, pin configurations and evaluation board information are included.
