AD8182AN

Overview

The AD8182AN is a dual-channel, high-speed 2-to-1 analog multiplexer manufactured by Analog Devices. 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 ±4 V to ±6 V supplies, consuming 6.8 mA when all channels are active. Key performance metrics include a channel switching time of 10 ns, an output settling time of 14 ns to 0.1%, and low glitch amplitude under 35 mV. It provides excellent video specifications, including 0.02% differential gain error and 0.02° differential phase error at 3.58 MHz.

Feature Summary

• Dual-channel architecture providing two independent 2-to-1 multiplexing paths within a single package.
• Fully buffered input and output stages ensure high isolation and unidirectional signal flow.
• Fast disable feature allows multiple devices to be connected in parallel without loading the output bus.
• Optimized for professional video applications with minimal differential gain and phase errors.

Applications

• Pixel switching for Picture-In-Picture (PIP) displays
• Switching in LCD and Plasma displays
• Video switchers and routers

Procurement Notes

Verify the specific ordering suffix to confirm the package type. The 'AN' designation indicates an 8-Lead Plastic DIP package. Ensure the procurement request matches this physical form factor to avoid compatibility issues during assembly or replacement.

Selection Notes

Select the AD8182AN when a dual-channel configuration is required for high-speed video routing. Consider the 14-lead plastic DIP package constraints regarding board space and thermal dissipation compared to surface-mount alternatives. Verify that the system power supply range aligns with the specified ±4 V to ±6 V operating limits.

Part Context

The AD8182AN belongs to the AD8180/AD8182 family of high-speed video multiplexers. While the AD8180 offers a single channel in an 8-lead package, the AD8182 integrates two channels into a 14-lead footprint. Both share identical electrical characteristics per channel, allowing designers to scale matrix complexity while maintaining consistent signal integrity and switching speeds.

Replacement Considerations

The AD8180ARZ serves as a functional substitute if only a single channel is needed, though it requires different pinout management. For direct dual-channel replacements, verify availability of other 14-lead SOIC variants from the same series, ensuring the package outline dimensions match the existing PCB footprint.
