AD8072JR

Overview

The AD8072JR is a dual current feedback video amplifier manufactured by Analog Devices Inc. It operates within a supply voltage range of ±2.5 V to ±6 V (single 5 V to 12 V). Key electrical specifications include a small-signal bandwidth of 100 MHz at a gain of +2, a slew rate of 500 V/µs, and a settling time of 25 ns to 0.1%. The device consumes 3.5 mA per amplifier and provides 30 mA output current. It features a differential gain error of 0.05% and a differential phase error of 0.1° at 3.58 MHz. The component is housed in an 8-lead SOIC package and functions over a commercial temperature range of 0°C to 70°C.

Feature Summary

• Provides high-speed signal processing with a 100 MHz bandwidth and 500 V/µs slew rate for video applications.
• Delivers low power consumption of 3.5 mA per amplifier while maintaining solid video performance into a 150 Ω load.
• Ensures accurate signal reproduction with minimal distortion, characterized by 0.05% differential gain error and 0.1° differential phase error.

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 against the manufacturer's official documentation to confirm the exact package type and temperature rating. Confirm that the procurement channel sources components directly from authorized distributors to ensure authenticity. Check for any recent product change notices regarding manufacturing sites or materials. Ensure the received units match the specified 8-lead SOIC form factor.

Selection Notes

Select this component for cost-sensitive, high-volume applications requiring reliable video signal amplification. Consider the 100 MHz bandwidth and fast settling time when designing circuits for general-purpose high-speed requirements. Evaluate the single 5 V to 12 V supply operation for compatibility with existing system power rails. Verify that the 30 mA output current capability meets the drive requirements of the connected loads.

Part Context

The AD8072JR belongs to the AD8072/AD8073 family of low-cost, current feedback amplifiers designed for business and consumer video electronics. While the AD8072 offers two amplifiers in an 8-lead package, the AD8073 variant integrates three amplifiers in a 14-lead package. Both devices share similar electrical characteristics but differ in pin count and physical size, allowing flexibility for space-constrained designs.

Replacement Considerations

The AD8072ARM serves as a direct replacement for the AD8072JR if industrial temperature range operation (-40°C to +85°C) is required. Both parts utilize the same 8-lead µSOIC/SOIC footprint and maintain identical electrical performance specifications.
