ADG2108BCPZ-R2

Overview

The ADG2108BCPZ-R2 is an I2C-compatible CMOS analog crosspoint switch featuring an 8 × 10 unbuffered array, totaling 80 bidirectional channels. It supports standard, fast, and high-speed (3.4 MHz) I2C interfaces with double-buffered input logic for simultaneous updates via the LDSW command. The device operates on dual ±5 V or single +12 V supplies, offering a maximum on-resistance of 35 Ω and low quiescent current below 20 µA. Packaged in a 32-lead LFCSP_WQ (5 mm × 5 mm), it provides up to 300 MHz bandwidth and includes a RESET function to open all switches at power-on.

Feature Summary

• I2C-compatible serial interface supporting standard, fast, and high-speed modes
• Bidirectional 8 × 10 analog switch array with simultaneous update capability
• Double-buffered input logic for synchronized channel configuration
• Power-on reset ensures all switches remain off during initialization

Applications

• AV switching in television systems
• Automotive infotainment routing
• CCTV signal distribution
• Ultrasound imaging applications
• KVM switching infrastructure

Procurement Notes

Verify the specific suffix R2 against official documentation to confirm reel packaging and tape specifications. Ensure the B version temperature range meets industrial requirements. Confirm pin compatibility with the 32-lead LFCSP_WQ footprint before integration.

Selection Notes

Select this component when a dense analog matrix with digital control is required. The I2C interface minimizes GPIO usage. Verify that the 35 Ω maximum on-resistance and 300 MHz bandwidth align with signal integrity needs. Consider the exposed paddle soldering requirement for thermal management.

Part Context

This part belongs to the ADG2108 family of analog crosspoint switches. It is distinct from multiplexers by its ability to connect multiple inputs to multiple outputs simultaneously. The B version denotes the industrial temperature grade, differing from the automotive Y version which supports higher temperatures.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate other Analog Devices crosspoint switches for pin and feature compatibility if substitution is necessary.
