ADG2128WBCPZ-REEL7

Overview

The ADG2128WBCPZ-REEL7 is an analog crosspoint switch array featuring a configuration of 8 columns by 12 rows, providing 96 independent bidirectional signal channels. It operates with dual ±5 V or single +12 V supplies and supports standard, fast, and high-speed (3.4 MHz) I²C interfaces. The device offers up to 300 MHz bandwidth, maximum on-resistance of 35 Ω, and low quiescent current below 20 µA. Packaged in a 32-lead LFCSP (5 mm × 5 mm), it includes double-buffered input logic for simultaneous updates and hardware reset capabilities.

Feature Summary

• I²C-compatible serial interface supporting standard, fast, and high-speed modes
• Double-buffered input logic enabling simultaneous update of multiple switches
• Hardware reset functionality ensuring all switches initialize to the off state
• Bidirectional signal routing with configurable row and column inputs/outputs

Applications

• AV switching in television systems
• Automotive infotainment signal routing
• KVM switching infrastructure
• Test equipment and instrumentation frontends
• PBX telecommunication systems

Procurement Notes

Verify the specific suffix WBCPZ-REEL7 against the manufacturer's official ordering guide to confirm package type, temperature grade, and reel quantity specifications. Ensure compatibility with the required I²C bus speed and supply voltage conditions before finalizing procurement orders.

Selection Notes

Select this component when a high-density 8x12 matrix is required for signal routing. Consider the B version industrial temperature range (-40°C to +85°C). Verify that the system requires the specific 3.4 MHz high-speed I²C capability if applicable, as this feature may be restricted to -HS models in other variants.

Part Context

This part belongs to the ADG2128 family of CMOS analog crosspoint switches manufactured by Analog Devices. It provides a flexible solution for routing analog and digital signals within a compact footprint, suitable for applications requiring extensive channel interconnection without external multiplexing components.

Replacement Considerations

Consult the official datasheet ordering guide for confirmed substitute part numbers. Verify pinout compatibility and electrical specifications before substituting.
