AD8187ARUZ-REEL7

Overview

The AD8187ARUZ-REEL7 is a high-speed, single-supply triple 2:1 multiplexer with a fixed gain of +2 V/V. It features a –3 dB bandwidth exceeding 480 MHz and a slew rate greater than 1500 V/µs. The device operates on a single 5 V supply, consuming approximately 20 mA. Key performance metrics include a channel-to-channel switching time of 4 ns, settling time to 0.1% within 7 ns, and off-isolation of –95 dB at 5 MHz. Differential gain and phase errors are limited to 0.05%. It utilizes a 24-lead TSSOP package.

Feature Summary

• Triple independent 2:1 multiplexing channels with internal gain-of-two configuration
• High-speed signal switching with minimal transient glitches
• High-impedance output disable feature for bus sharing applications
• TTL-compatible logic inputs with integrated reference buffering

Applications

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

Procurement Notes

Verify the obsolete status of this component series before procurement. Confirm that the REEL7 suffix corresponds to the 7-inch reel packaging option as specified in the ordering guide. Ensure compatibility with existing 24-lead TSSOP footprints and validate that the gain-of-two architecture meets system requirements without additional amplification stages.

Selection Notes

Select the AD8187 when a fixed voltage gain of two is required for the multiplexed signal path. This model differs from the AD8186, which provides unity gain. Consider the specific input/output voltage compliance limits relative to the 5 V supply rails. Ensure the application can accommodate the necessary VREF biasing for optimal dynamic range in single-supply configurations.

Part Context

This part belongs to the AD8186/AD8187 family of high-speed analog switches manufactured by Analog Devices Inc. The AD8187 variant is distinguished by its internal gain structure, providing a non-inverting gain of two. Both devices share identical pinouts and switching characteristics but differ in their signal amplification capabilities, catering to different video processing chain requirements.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The datasheet indicates the product line is obsolete. Designers should evaluate current Analog Devices multiplexer portfolios for modern equivalents with updated availability.
