AD8072JRZ

Overview

The AD8072JRZ is a dual-channel, low-cost current feedback video amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from +5 V to +12 V or dual supplies up to ±6 V. The device provides a small-signal bandwidth of 100 MHz at a gain of +2 and features a slew rate of 500 V/µs with a settling time of 25 ns to 0.1%. Each amplifier draws 3.5 mA of quiescent current and delivers an output current of 30 mA. Designed for driving back-terminated 150 Ω video loads, it offers excellent video specifications including 0.1 dB gain flatness to 10 MHz, 0.05% differential gain error, and 0.1° differential phase error.

Feature Summary

• Optimized for driving back-terminated 150 Ω video loads with high fidelity
• Provides solid video performance with minimal distortion and phase error
• Operates efficiently on single or dual power supplies with low current consumption
• Features fast transient response suitable for general-purpose high-speed applications

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 'JRZ' corresponds to the 8-lead SOIC package and commercial temperature range (0°C to 70°C). Confirm that the datasheet revision matches the required electrical characteristics, as parameters may vary between revisions. Ensure proper ESD handling procedures are followed during assembly due to the sensitivity of the CMOS input structure.

Selection Notes

Select this component when cost-sensitive, high-volume video processing is required alongside moderate speed requirements. It is suitable for designs needing a single +5 V supply operation with rail-to-rail-like swing capabilities within specified limits. Consider the 8-lead SOIC footprint constraints and ensure adequate thermal management if operating near maximum power dissipation limits.

Part Context

The AD8072 series includes the AD8072 (dual) and AD8073 (triple) variants, both designed for cost-effective, high-volume applications. While sharing core performance metrics like bandwidth and power consumption, the AD8073 integrates three amplifiers in a 14-lead package for space-constrained designs. The AD8072JRZ specifically denotes the dual-channel version in an 8-lead Small Outline Integrated Circuit (SOIC) package.

Replacement Considerations

The AD8072JR is a direct equivalent part number representing the same device without the RoHS-compliant 'Z' suffix. Other packages such as AD8072JN (DIP) or AD8072ARMZ (µSOIC) offer pin-compatible alternatives with different thermal or environmental ratings.
