AD8180AR-REEL

Overview

The AD8180AR-REEL is a high-speed 2-to-1 multiplexer manufactured by Analog Devices Inc. in an 8-lead SOIC package. It features a signal bandwidth exceeding 750 MHz and a slew rate of 750 V/µs. The device operates on ±5 V supplies with a quiescent current of 3.8 mA per channel. Key electrical parameters include a channel switching time of 10 ns, settling time to 0.1% at 14 ns, and low glitch amplitude under 35 mV. It provides excellent video specifications such as 0.02% differential gain error and 0.02° differential phase error.

Feature Summary

• Fully buffered inputs and outputs ensure unidirectional signal paths and minimal loading effects.
• Fast channel switching capability supports rapid transitions between input sources.
• High speed disable feature allows multiple devices to be connected for cascading stages without bus loading.

Applications

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

Procurement Notes

Verify the specific reel length suffix (e.g., REEL vs REEL7) against your manufacturing requirements. Confirm that the operating temperature range meets your environmental specifications. Ensure proper ESD handling procedures are followed during assembly due to the sensitivity of the CMOS bipolar process.

Selection Notes

Select this component when high bandwidth and fast settling times are critical for video signal integrity. Consider the AD8182 if dual-channel multiplexing is required within a single package. Evaluate power consumption constraints, as the device draws 3.8 mA per active channel at standard supply voltages.

Part Context

This part belongs to the AD8180/AD8182 family of high-speed video multiplexers. It shares architectural similarities with other Analog Devices RF switches but is optimized specifically for professional video applications requiring low distortion and high isolation.

Replacement Considerations

The AD8182 serves as a dual-channel alternative within the same product family. Verify pinout compatibility and functional equivalence before substituting with other multiplexer models from different manufacturers.

FAQ

How does the enable function affect the output state?

When the ENABLE input is HIGH, both buffers are disabled, and the output switches to a high impedance state, preventing the OFF channels from loading the output bus.

What is the maximum switching transient glitch magnitude?

The channel switching transient (glitch) is typically less than 35 mV when all inputs are grounded and driving a 1 kΩ load.
