AD8075ARU

Overview

The AD8075ARU 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. Key performance metrics include 0.01% differential gain error, 0.01° differential phase error, and 0.1 dB gain flatness up to 50 MHz. It offers superior isolation with all-hostile crosstalk better than –80 dB at 10 MHz and OFF isolation better than 90 dB. Quiescent current is less than 30 mA.

Feature Summary

• High-speed fully buffered inputs and outputs optimized for RGB video signals
• Fast output disable feature allowing outputs to enter a high-impedance state
• Excellent video specifications including low differential gain and phase errors
• Low power consumption with supply current under 30 mA on dual supplies

Applications

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

Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number AD8075ARU corresponds to the standard plastic TSSOP package. Suffixes such as Z indicate RoHS compliance, while REEL or REEL7 designations specify tape-and-reel packaging quantities. Confirm that the required package option matches the intended PCB footprint and assembly process before finalizing procurement orders.

Selection Notes

Select the AD8075ARU when a fixed voltage gain of +2 is required for triple-channel video applications. This component is distinct from the AD8074, which provides unity gain (G = +1). Ensure the design supports dual ±5 V power supplies and utilizes a 16-lead TSSOP footprint. Consider the fast settle time and high bandwidth requirements for high-resolution display driving tasks where minimal signal distortion is critical.

Part Context

The AD8075ARU belongs to the AD8074/AD8075 family of high-speed triple video buffers produced by Analog Devices Inc. These devices are engineered for demanding video processing environments requiring precise signal integrity. The AD8075 variant specifically addresses applications necessitating a gain of two, complementing the unity-gain AD8074 within the same product line.

Replacement Considerations

The AD8074 serves as a functional alternative within the same family but provides unity gain (G = +1) instead of the AD8075's gain of +2. Designers must account for this difference in amplification factor when substituting components.
