ADG2188BCPZ-HS-RL7

Overview

The ADG2188BCPZ-HS-RL7 is an I²C-compatible CMOS analog crosspoint switch featuring an 8 × 8 array of 64 bidirectional channels. It supports standard, fast, and high-speed (3.4 MHz) I²C interfaces with double-buffered input logic for simultaneous updates. The device operates on dual ±5 V or single +12 V supplies, offering a maximum on-resistance of 35 Ω and up to 300 MHz bandwidth. It includes hardware reset functionality, low quiescent current under 20 µA, and automotive qualification.

Feature Summary

• I²C-compatible interface supporting standard, fast, and high-speed modes
• Double-buffered input logic enabling simultaneous update of multiple switches
• Hardware reset option to clear all registers and open all switch channels
• Qualified for automotive applications

Applications

• AV switching in TV systems
• Automotive infotainment
• Test equipment and instrumentation

Procurement Notes

Verify the -HS suffix indicates support for the 3.4 MHz high-speed I²C mode. Confirm the B version temperature range (-40°C to +85°C) matches system requirements. Ensure the LFCSP_WQ package dimensions align with PCB layout constraints.

Selection Notes

Select this component when high-density signal routing is required via digital control. The high-speed I²C capability reduces bus latency compared to standard models. Verify that the 35 Ω maximum on-resistance meets signal integrity requirements for the specific application voltage levels.

Part Context

This part belongs to the ADG2188 family of analog crosspoint switches. The -HS suffix specifically denotes the inclusion of high-speed I²C interface capabilities. The B suffix identifies the industrial temperature grade variant within the product line.

Replacement Considerations

ADG2188BCPZ-REEL7: Standard I²C speed only. ADG2188YCPZ-RL7: Automotive grade with extended temperature range.
