AD8185ARUZ-REEL7

Overview

The AD8185ARUZ-REEL7 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 provides a –3 dB signal bandwidth up to 380 MHz at 200 mV p-p and 310 MHz at 2 V p-p, alongside a slew rate of 1150 V/µs for a 2 V step. It operates on ±5 V supplies with a quiescent current of 25 mA. Key specifications include 15 ns channel-to-channel switching time, –100 dB OFF isolation at 10 MHz, and excellent video performance metrics such as 0.01% differential gain error and 0.02° differential phase error.

Feature Summary

• Triple 2:1 Multiplexing Architecture
• High Speed Signal Processing
• Excellent Video Specifications
• Low Power Consumption

Applications

• Pixel Switching for Picture-In-Picture
• Switching RGB in LCD and Plasma Displays
• RGB Video Switchers and Routers

Procurement Notes

Verify the specific ordering suffix REEL7 indicates tape and reel packaging when sourcing components. Confirm that the Z suffix denotes RoHS compliance if required by project specifications. Ensure the selected variant matches the required temperature range and package dimensions for the intended PCB layout.

Selection Notes

Select the AD8185ARUZ-REEL7 over the AD8183 variant when a fixed voltage gain of +2 is required for the application. Consider the 24-lead TSSOP package constraints and verify power dissipation limits against ambient operating temperatures. Evaluate crosstalk requirements to ensure the device meets system isolation standards.

Part Context

This component belongs to the AD8183/AD8185 family of high-speed triple 2:1 multiplexers from Analog Devices. While sharing identical physical packages and core switching speeds, this specific model differs from the AD8183 by providing an internal voltage gain of +2 rather than unity gain. Both variants are designed for professional video and RGB multiplexing applications requiring fast settling times.

Replacement Considerations

The AD8183ARUZ-REEL7 serves as a functional substitute within the same family, provided the circuit design accommodates a unity gain configuration instead of the +2 gain offered by the AD8185. Verify that any replacement maintains the 24-lead TSSOP footprint and compatible logic voltage levels.
