AD8182ARZ

Overview

The AD8182ARZ is a dual high-speed 2-to-1 multiplexer manufactured by Analog Devices Inc. It operates on voltage supplies of ±5 V and features fully buffered inputs and outputs. The device provides a –3 dB signal bandwidth greater than 750 MHz, with a slew rate of 750 V/µs and a fast settling time of 14 ns to 0.1%. It consumes 6.8 mA of quiescent current when all channels are active. Key performance metrics include a channel switching time of 10 ns, low glitch magnitude of less than 35 mV, and excellent video specifications such as 0.02% differential gain error and 0.02° differential phase error. The component offers high 'OFF' isolation of –90 dB at 5 MHz and low all-hostile crosstalk of –80 dB at 5 MHz.

Feature Summary

• Fully buffered input and output architecture ensures unidirectional signal paths and minimal loading effects.
• Fast channel switching capability enables rapid transitions suitable for pixel-level operations.
• High speed operation supports wide bandwidth applications exceeding 750 MHz.
• Integrated high-speed disable feature allows multiple devices to be connected in parallel without bus loading.

Applications

• Pixel switching for Picture-In-Picture display systems
• Switching in LCD and Plasma displays
• Video switchers and routers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel configuration. Ensure that the selected variant matches the required temperature range and lead-free compliance standards for your manufacturing process. Cross-reference the datasheet revision to confirm pinout compatibility before integration into existing designs.

Selection Notes

Select this component for applications requiring high bandwidth and fast settling times in professional video environments. Consider the dual-channel configuration if space efficiency is critical compared to using single-channel units. Evaluate the power supply requirements carefully, as the device is optimized for ±5 V operation to achieve specified performance levels.

Part Context

The AD8182ARZ belongs to the AD8180/AD8182 family of high-speed multiplexers designed for demanding video and data acquisition applications. This series utilizes a proprietary dielectrically-isolated complementary bipolar process to achieve low power consumption alongside high performance. The dual-channel version complements the single-channel AD8180, offering integrated solutions for multi-signal routing.

Replacement Considerations

The AD8180ARZ serves as the single-channel counterpart within the same product family. When replacing components, verify that the pinout and functional logic remain compatible with the existing circuit design to ensure seamless integration without hardware modifications.

FAQ

How does the AD8182 handle multiple outputs connected together?

The device features a high-speed disable function that configures the output into a high impedance state. This allows multiple outputs to be connected in parallel for cascading stages while the OFF channels do not load the output bus.

What is the typical settling time for the AD8182ARZ?

The AD8182ARZ has a fast settling time of 14 ns to 0.1%, making it suitable for applications requiring precise signal acquisition within tight timing constraints.

Can the AD8182ARZ be used for picture-in-picture switching?

Yes, the 10 ns switching time and fast settling characteristics make the AD8182ARZ an excellent choice for pixel switching and picture-in-picture applications where clean transitions are critical to avoid screen artifacts.
