AD8188ARUZ-RL

Overview

The AD8188ARUZ-RL is a high-speed, single-supply triple 2:1 multiplexer manufactured by Analog Devices Inc. It features fully buffered inputs and outputs with a small-signal bandwidth of 350 MHz and a large-signal bandwidth of 300 MHz. The device operates on a single supply voltage ranging from 3.5 V to 5.5 V, consuming approximately 19 mA to 22.5 mA. Key performance metrics include a slew rate of 1000 V/μs, settling time to 0.1% in 7 ns, and channel-to-channel switching time of 4 ns. It offers excellent video specifications such as differential gain error of 0.05% and off-isolation of -95 dB at 5 MHz. The component is housed in a 24-lead TSSOP package.

Feature Summary

• Triple 2:1 multiplexing architecture with fully buffered inputs and outputs for signal integrity
• High-speed switching capabilities with fast settling times and minimal glitch transients
• Single-supply operation optimized for professional video applications with low power consumption
• High off-isolation and low crosstalk ensuring clear signal separation between channels

Applications

• Switching RGB signals in LCD and plasma displays
• RGB video switchers and routers
• Professional and component video multiplexing

Procurement Notes

Verify the specific ordering suffix RL indicates reel packaging when sourcing this component. Confirm that the part number corresponds to the AD8188 variant with unity gain (G=1), distinct from the AD8189 which has a gain of two. Ensure compatibility with standard surface-mount assembly processes for the 24-lead TSSOP package.

Selection Notes

Select the AD8188ARUZ-RL for applications requiring high-speed video signal routing with minimal distortion. Consider the single-supply constraint and ensure the input signal swing remains within the specified compliance range relative to the supply rails. Evaluate the need for AC coupling or DC restoration if operating near the supply limits.

Part Context

This component belongs to the AD8188/AD8189 family of high-speed analog multiplexers designed for demanding video environments. It provides a compact solution for managing multiple video sources in display systems. The ARUZ designation specifies the industrial temperature range and the TSSOP-24 surface-mount package format.
