AD8072ARM

Overview

The AD8072ARM 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 utilizes 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 supply voltages from 5 V to 12 V or dual supplies up to ±6 V. Key distortion metrics include a differential gain error of 0.05% and a differential phase error of 0.1°.

Feature Summary

• Provides high-speed video performance with low power consumption suitable for cost-sensitive applications
• Features excellent gain flatness and minimal differential gain and phase errors for accurate signal reproduction
• Capable of driving back-terminated loads with high output current capability

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 to confirm the package type and reel specifications. Confirm that the industrial temperature grade (-40°C to +85°C) matches the design requirements. Ensure ESD precautions are observed during handling due to the sensitivity of the internal circuitry. Cross-reference the datasheet revision to ensure all electrical characteristics align with the intended application parameters.

Selection Notes

Select this component when a low-cost, dual-channel solution is required for general-purpose high-speed applications. It is suitable for designs needing operation on a single 5 V supply or dual supplies up to ±6 V. Consider the 8-lead µSOIC package for space-constrained layouts. Verify that the feedback resistor values remain within the recommended range to maintain optimal gain flatness and stability.

Part Context

The AD8072ARM belongs to the AD8072/AD8073 family of low-cost, current feedback amplifiers designed for high-volume, cost-sensitive markets. While the standard AD8072 variants operate over the commercial temperature range (0°C to 70°C), the ARM suffix specifically denotes the industrial temperature extension. This family is optimized for driving 150 Ω video loads while maintaining solid video specifications.

Replacement Considerations

The AD8072JR serves as a direct functional substitute but is limited to the commercial temperature range (0°C to 70°C). For industrial temperature requirements, verify availability of other AD8072 variants with appropriate suffixes. No other cross-model replacements are confirmed in the provided documentation.
