AD8187ARUZ

Overview

The AD8187ARUZ is a high-speed, single-supply triple 2:1 multiplexer with a fixed gain of +2 V/V. It features a –3 dB large signal bandwidth exceeding 480 MHz and a slew rate greater than 1500 V/µs. The device settles to within 0.1% in 7 ns and consumes approximately 20 mA from a 5 V supply. It offers low differential gain error (0.05%) and phase error (0.05°), ensuring high video fidelity. The unit operates over a temperature range of –40°C to +85°C and is housed in a 24-lead TSSOP package.

Feature Summary

• Triple independent 2-to-1 multiplexing channels with internal gain-of-two configuration
• High-speed switching capability with minimal channel-to-channel transient glitches
• Fully buffered inputs and outputs for improved drive capability and isolation
• High impedance output disable feature for bus sharing and matrix expansion

Applications

• Switching RGB signals in LCD and plasma display systems
• RGB video switchers and routing matrices
• Professional component video multiplexing applications

Procurement Notes

Verify the specific ordering suffix ARU corresponds to the 24-lead TSSOP package variant. Confirm that the revision level matches current manufacturing standards, as older revisions may be marked obsolete. Ensure compatibility with standard surface-mount assembly processes for thin shrink small outline packages.

Selection Notes

Select this model when a fixed voltage gain of two is required for the multiplexed signals. Compare against the AD8186 if unity gain buffering is preferred instead. Consider the single-supply operation constraints and verify that the input common-mode range aligns with the system's reference voltage requirements for optimal dynamic range.

Part Context

This component belongs to the AD8186/AD8187 family of high-speed analog switches. The primary distinction between these variants lies in their internal gain structure; the AD8187 provides a gain of two, whereas the AD8186 operates at unity gain. Both share identical pinouts, switching speeds, and power consumption characteristics within the same package footprint.
