AD8072ARM-REEL

Overview

The AD8072ARM-REEL is a dual current feedback video amplifier manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-lead µSOIC package. The device features a small-signal bandwidth of 100 MHz at a gain of +2, with a slew rate of 500 V/µs and a settling time of 25 ns to 0.1%. It consumes 3.5 mA per amplifier and supports single or dual power supplies ranging from ±2.5 V to ±6 V (5 V to 12 V). Key video performance metrics include 0.05% differential gain error and 0.1° differential phase error.

Feature Summary

• Optimized for driving back-terminated 150 Ω video loads while maintaining low power consumption.
• Provides high-speed signal processing capabilities suitable for general-purpose applications requiring fast settling times.
• Features accessible inputs and outputs on each channel to allow flexible gain setting configurations.

Applications

• Video line driver circuits
• Computer video plug-in boards
• RGB or S-video amplifiers in component systems

Procurement Notes

Verify the specific ordering suffix REEL against the manufacturer's documentation to confirm reel specifications and quantity limits. Ensure that the industrial temperature rating (-40°C to +85°C) aligns with the operational environment requirements. Cross-reference the 8-lead µSOIC package dimensions with the PCB footprint design to ensure mechanical compatibility during assembly.

Selection Notes

Select this component when cost-sensitive designs require dual-channel video amplification with high bandwidth. Consider the 30 mA output current capability for direct drive applications without additional buffering. Evaluate the trade-off between the fixed feedback resistor recommendations and the desired system noise bandwidth before finalizing the circuit topology.

Part Context

This part belongs to the AD8072/AD8073 family of low-cost video amplifiers designed for high-volume consumer electronics. While the AD8073 offers triple channels in a 14-lead package, the AD8072 provides dual channels in an 8-lead format. The ARM variant specifically denotes the industrial temperature grade and µSOIC packaging, distinguishing it from commercial grade SOIC or DIP options.

Replacement Considerations

Direct substitutes within the same family include the AD8072JR for commercial temperature ranges or the AD8072JN for plastic DIP packaging. Verify pinout compatibility and thermal dissipation characteristics when transitioning between different package types such as SOIC versus µSOIC.
