AD8141ACPZ-R2

Overview

The AD8141ACPZ-R2 is a triple, low-cost differential driver manufactured by Analog Devices Inc. It features three independent channels with a fixed gain of 2 V/V, designed to compensate for line termination attenuation. The device operates on a single 5 V supply or split supplies within a 4.5 V to 5.5 V range. Key electrical specifications include a 275 MHz small-signal bandwidth, a 255 MHz large-signal bandwidth, and a 65 MHz bandwidth for 0.1 dB flatness. It exhibits a slew rate of 1150 V/µs and a settling time of 12 ns. The package is a 24-lead LFCSP (4 mm × 4 mm) operating from -40°C to +85°C.

Feature Summary

• Triple high-speed differential drivers optimized for wideband video applications
• Internal common-mode feedback network ensures output amplitude and phase matching
• Fixed gain of 2 V/V to compensate for line termination resistor attenuation
• Disable feature provides high-Z outputs for line isolation and multiplexing

Applications

• Keyboard-video-mouse (KVM) networking
• Video distribution systems
• Digital signage displays
• Security camera signal transmission

Procurement Notes

Verify the specific suffix R2 indicates reel packaging when sourcing. Confirm the component matches the AD8141 functional description rather than the AD8142 sync-on-common-mode variant. Ensure the order quantity aligns with manufacturer reel specifications. Check for RoHS compliance documentation as required by regional regulations.

Selection Notes

Select this component for RGB signal processing where cost-effective CMOS performance is required. It supports both differential-to-differential and single-ended-to-differential conversion. Consider the AD8142 if integrated horizontal and vertical sync embedding on common-mode lines is necessary. Verify power supply constraints fit the 5 V single-supply operation profile.

Part Context

This part belongs to the AD8141/AD8142 family of triple differential drivers. These devices are engineered for high-resolution video transmission over UTP cables. They complement receivers like the AD8145 and equalizers such as the AD8123 in complete video distribution architectures. The technology utilizes a specialized CMOS process for fast settling times.

Replacement Considerations

The AD8142 serves as a functional alternative within the same series but includes integrated sync-on-common-mode circuitry not present in the AD8141. Other family members include the AD8146, AD8147, and AD8148. Verify pin compatibility and specific feature requirements before substitution.
