AD8180ARZ

Overview

The AD8180ARZ is a single-channel, high-speed 2-to-1 multiplexer manufactured by Analog Devices Inc. It operates on dual voltage supplies of ±5 V and consumes 3.8 mA of quiescent current. The device features fully buffered inputs and outputs with a –3 dB signal bandwidth exceeding 750 MHz and a slew rate of 750 V/µs. Key switching characteristics include a channel switching time of 10 ns and a settling time to 0.1% of 14 ns. It provides excellent video specifications, including 0.02% differential gain error and 0.02° differential phase error at 3.58 MHz. The component offers low glitch magnitude (<35 mV), high 'OFF' isolation (–90 dB @ 5 MHz), and fast output disable capability for cascading multiple devices.

Feature Summary

• Fully buffered input and output architecture ensures unidirectional signal paths and minimal loading effects.
• Fast channel switching and enable/disable functions allow clean transitions suitable for pixel-level operations.
• High off-isolation and low all-hostile crosstalk maintain signal integrity in multi-channel systems.
• Low power consumption design supports efficient operation in portable or dense electronic environments.

Applications

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

Procurement Notes
