ADG2188BCPZ-REEL7

Overview

The ADG2188BCPZ-REEL7 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 low quiescent current under 20 µA. It provides up to 300 MHz bandwidth, -69 dB off-isolation, and includes hardware reset functionality. Packaged in a 32-lead LFCSP_WQ (5 mm × 5 mm), it is qualified for automotive applications.

Feature Summary

• I²C-compatible interface supporting standard, fast, and high-speed modes
• Double-buffered input logic enabling simultaneous update of multiple switches
• Bidirectional 8 × 8 analog switch array with configurable inputs and outputs
• Hardware reset capability ensuring all switches initialize to the off state

Applications

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

Procurement Notes

Verify the specific suffix against official documentation to confirm temperature range and automotive qualification status. Ensure the ordering code matches the required industrial or extended operating specifications. Confirm package type and reel packaging details align with manufacturing requirements before finalizing procurement orders.

Selection Notes

Select this component when a dense, digitally controlled signal routing matrix is required. The I²C interface minimizes digital pin count, while the bidirectional nature of the X and Y lines offers flexible system design. Consider the 35 Ω maximum on-resistance and 300 MHz bandwidth limits for high-frequency signal integrity requirements.

Part Context

This part belongs to the Analog Devices ADG21 series of analog crosspoint switches. It is designed for applications requiring high channel density and precise signal routing control via a serial interface. The device integrates both analog switching capabilities and digital control logic into a compact surface-mount package.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers. Cross-reference electrical parameters such as on-resistance, bandwidth, and supply voltage ranges to ensure compatibility with existing circuit designs.
