AD8182AR-REEL7

Overview

The AD8182AR-REEL7 is a dual high-speed 2-to-1 multiplexer manufactured by Analog Devices Inc. It features fully buffered inputs and outputs with a small-signal bandwidth exceeding 750 MHz and a slew rate of 750 V/µs. The device operates on a single -5 V supply, consuming 6.8 mA of quiescent current. Key performance metrics include a channel switching time of 10 ns, an output settling time to 0.1% of 14 ns, and low glitch energy under 35 mV. It provides excellent video specifications, including 0.02% differential gain error and 0.028° differential phase error at 3.58 MHz. The component offers high OFF isolation of -90 dB at 5 MHz and all-hostile crosstalk of -80 dB at 5 MHz. It is housed in a 14-lead SOIC package.

Feature Summary

• Fully buffered architecture providing unidirectional signal paths with minimal switching glitches.
• High-speed disable feature allowing multiple devices to be connected in parallel without loading the output bus.
• Excellent video fidelity characterized by low differential gain and phase errors for professional applications.
• Low power consumption suitable for battery-operated or thermally constrained systems.

Applications

• Pixel switching for Picture-In-Picture display implementations
• Signal routing in LCD and Plasma display systems
• Video switchers and routers requiring high bandwidth

Procurement Notes

Verify the specific ordering suffix REEL7 indicates a 7-inch reel packaging configuration as defined in the manufacturer's ordering guide. Confirm that the AR variant corresponds to the narrow SOIC package option. Ensure compatibility with -5 V supply requirements and TTL-compatible logic levels for SELECT and ENABLE inputs during integration.

Selection Notes

Select this component when dual-channel multiplexing with high bandwidth and fast settling times are required. Consider the AD8180 if only a single channel is needed to reduce cost and board space. Evaluate the AD8184 if four input channels are necessary for more complex matrix configurations. Verify that the 14-lead SOIC footprint fits the available PCB layout constraints.

Part Context

The AD8182 belongs to the AD8180/AD8182 family of high-speed video multiplexers designed for professional video applications. These devices utilize a proprietary dielectrically-isolated complementary bipolar process to achieve wide bandwidth and low power dissipation. The family includes the single-channel AD8180 and the dual-channel AD8182, both sharing similar electrical characteristics and pinout compatibility where applicable.
