AD8182ARZ-R7

Overview

The AD8182ARZ-R7 is a dual 2-to-1 buffered multiplexer manufactured by Analog Devices Inc. It operates on a single -5 V supply and features a small-signal bandwidth exceeding 750 MHz with a slew rate of 750 V/µs. The device achieves a channel switching time of 10 ns and settles to 0.1% accuracy within 14 ns. Quiescent current consumption is 6.8 mA when all channels are active. Key performance metrics include an off-isolation of -93 dB at 5 MHz, crosstalk of -78 dB at 5 MHz, and differential gain error of 0.02%. The component is housed in a 14-lead SOIC package.

Feature Summary

• Fully buffered input and output architecture ensures high isolation and unidirectional signal flow.
• Fast switching capability allows for clean transitions suitable for pixel-level video applications.
• High-speed disable feature enables outputs to enter a high impedance state for cascading multiple devices.
• Low glitch magnitude minimizes transient artifacts during channel selection.

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 REEL7 suffix indicates a 7-inch reel packaging format as defined in the manufacturer's ordering guide. Confirm that the ARZ designation corresponds to the specified operating temperature range and lead-free compliance standards required for the target assembly process.

Selection Notes

Select this component when a dual-channel configuration is required to save board space compared to using two single-channel units. Ensure the system can accommodate the -5 V supply voltage requirement. Verify that the 14-lead SOIC footprint aligns with the available PCB layout constraints and thermal dissipation capabilities.

Part Context

This part belongs to the AD8180/AD8182 family of high-speed video multiplexers. While the AD8180 provides a single 2-to-1 mux in an 8-lead package, the AD8182 integrates two such channels into a 14-lead package. Both share identical electrical characteristics and pinout logic for their respective channels.

Replacement Considerations

The AD8180ARZ serves as a functional substitute if only one 2-to-1 multiplexer channel is needed, though it requires an 8-lead package instead of 14 leads.

FAQ

How does the ENABLE pin affect the output state?

When the ENABLE input is driven HIGH, both buffers are disabled, and the output switches to a high impedance state regardless of the SELECT input level.

What is the maximum power dissipation for the 14-lead SOIC package?

The maximum safe junction temperature is approximately +150°C. For the 14-lead SOIC package, the thermal resistance (θJA) is 120°C/W, limiting the maximum power dissipation based on ambient temperature conditions.

Can multiple AD8182 devices be connected together?

Yes, the fast output disable feature allows multiple outputs to be wired in parallel. When disabled, the high impedance state prevents loaded channels from degrading the signal on the shared bus.
