AD8073JRZ-REEL

Overview

The AD8073JRZ-REEL is a low-cost, triple current feedback video amplifier manufactured by Analog Devices Inc. It integrates three independent amplifiers within a single 14-lead narrow-body SOIC package. The device operates on a single supply voltage ranging from +5 V to +12 V or dual supplies up to ±6 V. Key electrical specifications include a 100 MHz bandwidth, a 500 V/µs slew rate, and a settling time of 25 ns to 0.1%. Each channel consumes 3.5 mA of quiescent current and provides 30 mA of output drive capability into a 150 Ω load.

Feature Summary

• Integrates three independent high-speed amplifiers in a compact 14-lead SOIC package for space-constrained designs.
• Optimized for driving back-terminated video loads with excellent gain flatness and minimal differential gain/phase errors.
• Supports flexible power configurations including single +5 V to +12 V or dual ±6 V supplies.
• Features internal short-circuit protection and robust overdrive recovery capabilities.

Applications

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

Procurement Notes

Verify the specific ordering suffix (e.g., REEL vs. REEL7) against the manufacturer's official documentation to ensure correct packaging quantity and reel size compatibility. Confirm that the commercial temperature range (0°C to +70°C) aligns with the operational environment requirements. Cross-reference the pinout configuration for the 14-lead SOIC package during schematic capture to prevent layout errors.

Selection Notes

Select this component when multiple identical high-speed amplification channels are required within a limited board area. The current feedback architecture offers superior slew rate performance compared to voltage feedback alternatives at similar costs. Ensure the application requires operation within the specified single or dual supply ranges and can accommodate the necessary feedback resistor values for optimal bandwidth stability.

Part Context

This part belongs to the AD8072/AD8073 family of low-cost video amplifiers designed for high-volume consumer electronics. While the AD8072 provides two channels in an 8-lead package, the AD8073 expands this functionality to three channels. Both devices share identical core performance characteristics but differ in channel count and physical footprint, allowing designers to scale complexity without changing the fundamental circuit topology.

Replacement Considerations

The AD8073JR is the non-reel variant of this component. The AD8073JN is available in a 14-lead plastic DIP package for through-hole applications. No direct functional substitutes are documented in the provided datasheet; alternative packages within the same series should be verified for pin compatibility.
