ADG2128BCPZ-HS-RL7

Overview

The ADG2128BCPZ-HS-RL7 is an I²C-compatible CMOS analog crosspoint switch featuring an 8 × 12 matrix, providing 96 independent bidirectional signal channels. It supports standard, fast, and high-speed (3.4 MHz) I²C interfaces, with the -HS suffix enabling the high-speed option. 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. 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

• Supports high-speed I²C interface at 3.4 MHz
• Features double-buffered input logic for simultaneous switch updates
• Includes hardware reset functionality to open all switches

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required I²C speed capability. Confirm the package type and temperature range align with the design specifications before finalizing procurement orders.

Selection Notes

Select this variant specifically when high-speed serial communication at 3.4 MHz is required. Ensure the power supply configuration matches the specified dual or single voltage requirements for optimal performance.

Part Context

This component belongs to the ADG2128 family of analog crosspoint switches. The -HS suffix indicates support for the high-speed I²C interface, distinguishing it from standard variants limited to lower clock frequencies.

Replacement Considerations

Standard ADG2128BCPZ variants lack the high-speed I²C feature. Verify if the system controller supports 3.4 MHz operation before substituting.
