AD8182AR-REEL

Overview

The AD8182AR-REEL is a dual 2-to-1 high-speed video multiplexer manufactured by Analog Devices Inc. It operates on a single +5 V supply and consumes 6.8 mA of quiescent current with both channels active. The device features a small-signal bandwidth exceeding 750 MHz and a slew rate of 750 V/µs. Key performance metrics include a channel switching time of 10 ns, a settling time to 0.1% of 14 ns, and an input offset voltage of 2 mV. It provides excellent video specifications such as 0.02% differential gain error and -93 dB OFF isolation at 5 MHz. The component is housed in a 14-lead SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Fully buffered inputs and outputs ensure high impedance signal handling and low loading effects.
• Fast channel switching capability allows for clean transitions suitable for pixel-level operations.
• High OFF isolation and low crosstalk maintain signal integrity in multi-channel environments.
• Integrated disable feature enables outputs to enter a high-impedance state for bus cascading.

Applications

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

Procurement Notes

Verify the specific suffix REEL against the manufacturer's ordering guide to confirm the 13-inch reel packaging option. Ensure the design accommodates the 14-lead SOIC footprint and thermal requirements for the plastic package. Confirm that the logic levels for SELECT and ENABLE pins match the system interface voltages.

Selection Notes

Select this component when dual independent 2-to-1 multiplexing is required within a single package. Compare the 750 MHz bandwidth against system frequency needs. Evaluate the 6.8 mA power consumption against available supply rails. Consider the AD8180 if only a single channel is needed to reduce board space.

Part Context

This part belongs to the AD8180/AD8182 family of high-speed video multiplexers. The AD8182 specifically integrates two independent 2-to-1 switches, whereas the AD8180 contains a single channel. Both share identical electrical characteristics and are designed for professional video applications requiring fast settling and low distortion.

Replacement Considerations

Public confirmed substitute part numbers are not identified in the provided documentation. Designers should consult the manufacturer's official documentation for any recommended upgrades or legacy replacements.

FAQ

How does the AD8182 achieve low glitch during switching?

The device utilizes a switched open-loop buffer architecture with dedicated flatness circuits and decoder logic that translates TTL-compatible inputs to internal ECL levels, minimizing switching transients.

What is the function of the ENABLE pin?

Driving the ENABLE pin HIGH forces both buffers into a disabled state, placing the output in a high-impedance state. This allows multiple devices to be connected in parallel without loading the output bus.

Can the AD8182 drive capacitive loads directly?

Yes, the device includes dedicated flatness circuits that keep peaking low (typically < 1 dB) even when driving high capacitive loads, though increasing load capacitance will reduce bandwidth.
