AD8182ARZ-RL

Overview

The AD8182ARZ-RL is a dual high-speed 2-to-1 multiplexer manufactured by Analog Devices Inc. It features fully buffered inputs and outputs with a –3 dB signal bandwidth exceeding 750 MHz and a slew rate of 750 V/µs. The device operates on ±5 V supplies, consuming 6.8 mA when all channels are active. It offers fast channel switching of 10 ns and settling to 0.1% in 14 ns. Key performance metrics include low glitch amplitude (<35 mV), excellent video specifications (0.02% differential gain error), and high OFF isolation (-93 dB). The component is housed in a 14-lead SOIC package.

Feature Summary

• Dual 2-to-1 multiplexing architecture with fully buffered input and output stages
• High-speed operation with greater than 750 MHz bandwidth and 750 V/µs slew rate
• Fast channel switching capability with 10 ns transition time
• Low power consumption at 6.8 mA quiescent current for the dual configuration

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Ensure that the selected variant matches the required lead frame and reel specifications for your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and compliance with regional regulatory standards.

Selection Notes

Select this component for applications requiring high bandwidth and fast switching speeds. Consider the dual-channel configuration if multiple independent 2-to-1 selections are needed within a single package. Evaluate the power supply requirements, as the device is designed for ±5 V operation. Ensure the PCB layout supports high-frequency performance by minimizing parasitic capacitance and inductance.

Part Context

The AD8182 is part of the AD8180/AD8182 family of high-speed video multiplexers. It shares architectural similarities with the single-channel AD8180 but provides two independent multiplexing channels in a 14-lead package. This family is designed for professional video applications where signal integrity and speed are critical.

Replacement Considerations

The AD8180 serves as the single-channel equivalent within the same product family. For direct replacement, verify pin compatibility and ensure the application does not require the second channel provided by the AD8182.

FAQ

How does the AD8182 handle output disabling?

The device features a high-speed disable function that allows the output to be configured into a high impedance state, enabling multiple outputs to be connected together without loading the output bus.

What is the typical OFF isolation performance?

The AD8182 provides high OFF isolation, typically -93 dB at 5 MHz, ensuring minimal signal leakage when a channel is disabled.

Is the AD8182 suitable for pixel switching applications?

Yes, the 10 ns switching time makes it an excellent choice for pixel switching and Picture-In-Picture applications where fast transitions are required.
