AD8188ARUZ-R7

Overview

The AD8188ARUZ-R7 is a high-speed, single-supply triple 2:1 multiplexer manufactured by Analog Devices Inc. It features fully buffered inputs and outputs with a small-signal bandwidth of 350 MHz and a large-signal bandwidth of 300 MHz at 2 V p-p. The device operates on a single supply voltage ranging from 3.5 V to 5.5 V, consuming approximately 19 mA to 20 mA. Key performance metrics include a slew rate of 1000 V/μs, a settling time of 7 ns to 0.1%, and low glitch energy. It provides excellent video specifications such as 0.05% differential gain error and -84 dB all-hostile crosstalk at 5 MHz. The component is housed in a 24-lead TSSOP package.

Feature Summary

• Fully buffered input and output stages for signal integrity
• High-speed switching capability with minimal transient glitches
• Single-supply operation optimized for 5 V systems
• High off-isolation and low crosstalk for multi-channel applications

Applications

• Switching RGB signals in LCD and plasma displays
• RGB video switchers and routers
• Professional and component video multiplexing

Procurement Notes

Verify the R7 suffix indicates reel packaging when sourcing. Confirm the specific part number against official distributor catalogs to ensure authenticity. Check for RoHS compliance documentation if required by local regulations. Ensure storage conditions align with manufacturer guidelines to prevent moisture damage prior to soldering.

Selection Notes

Select this component for applications requiring fast channel-to-channel switching and high bandwidth. Consider the AD8189 variant if a voltage gain of two is necessary instead of unity gain. Evaluate power consumption requirements against the typical 19 mA quiescent current. Ensure the system design accommodates the 24-lead TSSOP footprint and thermal dissipation limits.

Part Context

This component belongs to the AD8188/AD8189 family of high-speed analog multiplexers designed for video processing. It serves as a critical interface for routing multiple video sources to a single display or processing unit. The device integrates logic control for simultaneous channel selection and output enable functions within a compact surface-mount package.

Replacement Considerations

The AD8189ARUZ-R7 is a functional substitute offering a gain of two. Verify pin compatibility and electrical characteristics before substitution. Other series components may require circuit redesign due to differing bandwidth or supply voltage specifications.
