AD8187ARUZ-REEL

Overview

The AD8187ARUZ-REEL is a high-speed, single-supply triple 2:1 multiplexer with a fixed gain of +2. It features fully buffered inputs and outputs, offering 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 low glitch energy. It provides excellent video specifications with 0.05% differential gain error and 0.05° differential phase error at 150 Ω loads. Off-isolation reaches –95 dB at 5 MHz, ensuring minimal signal interference between channels.

Feature Summary

• Triple independent 2:1 multiplexing channels with fixed non-inverting gain of two
• High-speed analog switching with fast channel-to-channel transition times
• Fully buffered input and output stages for improved drive capability and isolation
• High impedance output disable feature for bus sharing and matrix construction

Applications

• Switching RGB signals in LCD and plasma display systems
• RGB video switchers and routing matrices
• Professional component video multiplexing applications

Procurement Notes

Verify the specific ordering suffix REEL against current manufacturer documentation to confirm reel size and packaging configuration. Confirm that the obsolete status does not impact long-term availability or support requirements for your design lifecycle. Ensure compatibility with existing PCB footprints for the 24-lead TSSOP package before finalizing procurement decisions.

Selection Notes

Select this component when a fixed gain of two is required for the multiplexed signal path. The AD8186 variant should be considered if unity gain is preferred. Evaluate the single-supply voltage headroom constraints, particularly regarding the VREF pin biasing requirements for the gain-of-two architecture. Ensure the application can accommodate the specified operating temperature range and power dissipation limits in the TSSOP package.

Part Context

This part belongs to the AD8186/AD8187 family of high-speed video multiplexers manufactured by Analog Devices Inc. The AD8187 specifically denotes the version with an internal gain of two, distinguishing it from the unity-gain AD8186. Both devices share the same pinout and functional block diagram but differ in their internal feedback networks. The REEL suffix indicates tape-and-reel packaging for automated assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Designers should consult Analog Devices for current alternative recommendations or cross-reference options based on specific bandwidth and gain requirements.
