AD8180ARZ-R7

Overview

The AD8180ARZ-R7 is a high-speed, single-channel 2-to-1 multiplexer manufactured by Analog Devices Inc. It features fully buffered inputs and outputs with a –3 dB signal bandwidth exceeding 750 MHz (typical 930 MHz at RL = 5 kΩ) and a slew rate of 750 V/µs. The device operates on ±5 V supplies, consuming 3.8 mA quiescent current. Key performance metrics include a channel switching time of 10 ns, a 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 0.02° differential phase error. The component offers a fast output disable feature for cascading multiple devices and is housed in an 8-lead SOIC package.

Feature Summary

• Fully buffered input and output architecture ensures unidirectional signal paths and constant low input capacitance independent of load impedance.
• Fast channel switching capability with 10 ns transition times suitable for pixel-level operations.
• High-speed disable feature allows outputs to be configured into a high-impedance state for cascading stages without loading the output bus.
• Low glitch magnitude and high off-isolation minimize signal artifacts during transitions.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'R7' corresponds to the 7-inch reel packaging configuration as defined in the manufacturer's ordering guide. Confirm that the 'A' grade designation meets the required DC transfer characteristics and offset voltage tolerances for the intended application environment.

Selection Notes

Select this component when designing systems requiring wide bandwidth greater than 750 MHz and fast settling times below 15 ns. Ensure the power supply rails are maintained within the ±4 V to ±6 V operating range. Consider the 8-lead SOIC package constraints for PCB layout, specifically regarding ground plane removal near pins to minimize stray capacitance.

Part Context

This part belongs to the AD8180 family of high-speed video multiplexers. It serves as the single-channel counterpart to the dual-channel AD8182. Both devices share identical electrical specifications and architectural features but differ in pin count and channel density, with the AD8180 utilizing an 8-lead package compared to the 14-lead package of the AD8182.

Replacement Considerations
