AD8075ARU-REEL7

Overview

The AD8075ARU-REEL7 is a high-speed triple video buffer with a fixed gain of +2, manufactured by Analog Devices Inc. It operates on dual ±5 V supplies and features a –3 dB full signal bandwidth exceeding 450 MHz, reaching 600 MHz at 200 mV p-p output. The device exhibits a slew rate of 1350 V/µs and a fast settling time of 4 ns to 0.1%. Key performance metrics include 0.01% differential gain error, 0.01° differential phase error, and less than 30 mA quiescent current. It incorporates a fast output disable feature for high isolation.

Feature Summary

• Triple-channel architecture with fixed voltage gain of +2
• High-speed fully buffered inputs and outputs optimized for video signals
• Fast output disable feature allowing outputs to enter a high-impedance state
• Low power consumption with supply current under 30 mA

Applications

• RGB buffering in LCD and plasma displays
• RGB driver circuits
• Video routers and multiplexers

Procurement Notes

Verify the specific ordering suffix REEL7 indicates tape and reel packaging configuration. Confirm RoHS compliance status associated with the Z designation if applicable to the specific batch. Ensure the component matches the RU-16 package outline dimensions. Validate that the operating temperature range meets system requirements of -40°C to +85°C. Check datasheet revision history for any parameter updates.

Selection Notes

Select this component when a gain of +2 is required for driving reverse-terminated video loads. Compare against the AD8074 if unity gain buffering is sufficient. Consider the fast settling time and low distortion for high-resolution graphics applications. Evaluate the disable feature for multiplexer designs requiring channel isolation. Ensure power supply constraints align with the dual ±5 V requirement.

Part Context

This part belongs to the AD8074/AD8075 family of high-speed triple video buffers from Analog Devices. The AD8075 variant specifically provides a gain of +2, whereas the AD8074 offers unity gain. Both share similar bandwidth and slew rate characteristics but differ in internal feedback network configuration. The family is designed for demanding video processing tasks requiring minimal signal degradation.

Replacement Considerations

The AD8074 serves as a functional alternative within the same family but provides unity gain instead of +2. Direct pin-compatible substitutes are not explicitly listed in the provided documentation. Verify electrical compatibility regarding bandwidth and drive capability before considering other manufacturers' parts.
