ADG2188YCPZ-REEL7

Overview

The ADG2188YCPZ-REEL7 is an I²C-controlled analog crosspoint switch featuring an 8 × 8 matrix of 64 bidirectional channels. It supports dual ±5 V or single +12 V supplies, with a maximum on-resistance of 35 Ω and low quiescent current under 20 µA. The device accommodates standard, fast, and high-speed (up to 3.4 MHz) I²C interfaces, double-buffered logic, and simultaneous switch updates via the LDSW command. It operates within −40°C to +125°C, offers up to 300 MHz bandwidth, and includes hardware reset functionality.

Feature Summary

• I²C-compatible serial interface supporting standard, fast, and high-speed modes
• Bidirectional 8 × 8 analog switch array with flexible input/output configuration
• Simultaneous multi-switch update capability using the LDSW command
• Hardware reset pin for immediate switch deactivation and register clearing

Applications

• AV switching in television systems
• Automotive infotainment routing
• CCTV signal distribution
• Ultrasound imaging applications
• Test equipment and instrumentation

Procurement Notes

Verify the Y suffix indicates the automotive-grade variant rated for −40°C to +125°C operation. Confirm the REEL7 designation matches the required tape-and-reel packaging format. Ensure the specific revision aligns with your design requirements, as Analog Devices may issue updates without notice.

Selection Notes

Select this component when a dense 64-channel routing matrix is required alongside digital control flexibility. The dual-supply capability allows compatibility with both single-ended and differential signal paths. Verify that the 35 Ω maximum on-resistance meets the voltage drop constraints of your specific application signals.

Part Context

This part belongs to the ADG2188 family of CMOS analog crosspoint switches. It provides a compact solution for complex signal routing tasks where minimizing board space is critical. The LFCSP_WQ package facilitates surface-mount assembly while maintaining thermal performance through the exposed paddle connection.

Replacement Considerations

Direct substitutes include other ADI 8x8 crosspoint switches like the ADG2108, though channel counts differ. Verify pinout compatibility and I²C address configurations before swapping components to ensure seamless integration into existing designs.
