AD8185ARUZ-REEL

Overview

The AD8185ARUZ-REEL is a high-speed triple 2:1 multiplexer manufactured by Analog Devices Inc. It features fully buffered inputs and outputs with a voltage gain of +2. The device operates on ±5 V supplies, consuming 25 mA quiescent current. Key electrical parameters include a –3 dB bandwidth of 380 MHz at 200 mV p-p and 310 MHz at 2 V p-p into a 150 Ω load. It exhibits a slew rate of 1150 V/µs for a 2 V step and settles to 0.1% within 15 ns. The component offers –100 dB OFF isolation at 10 MHz and low channel-to-channel crosstalk of –56 dB at 100 MHz. It is housed in a 24-lead TSSOP package.

Feature Summary

• Fully buffered input and output architecture ensures signal integrity and drive capability.
• High-speed switching with 15 ns channel-to-channel transition time minimizes signal glitches.
• Integrated high-impedance output disable feature allows safe connection of multiple devices.
• Optimized video specifications including low differential gain and phase errors.

Applications

• Pixel switching for Picture-in-Picture displays
• RGB signal switching in LCD and Plasma displays
• RGB video switchers and routers

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging rather than tube. Confirm RoHS compliance status as indicated by the Z suffix in standard variants. Ensure the operating temperature range matches system requirements. Check for specific lot traceability if required by quality standards.

Selection Notes

Select this model over the AD8183 when a voltage gain of +2 is required for the multiplexing application. Verify that the 24-lead TSSOP package fits the PCB layout constraints. Ensure the power supply rails are stable at ±5 V to maintain specified performance metrics.

Part Context

This component belongs to the AD8183/AD8185 family of high-speed triple 2:1 multiplexers from Analog Devices. While sharing similar switching speeds and package types, the AD8185 differs from the AD8183 by providing a fixed voltage gain of +2, whereas the AD8183 provides unity gain.

Replacement Considerations

The AD8183ARUZ-REEL serves as a functional substitute if unity gain (G=+1) is acceptable instead of the AD8185's gain of +2. Other family members like the AD8185ARU-REEL7 offer identical functionality in reel packaging.
