AD8072JNZ

Overview

The AD8072JNZ 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 parameters include a –3 dB 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 an input offset voltage of 4 mV and input bias current of 10 µA. The component is housed in an 8-lead plastic DIP package and supports commercial operating temperatures from 0°C to 70°C.

Feature Summary

• Provides high-speed signal processing with 100 MHz bandwidth and 500 V/µs slew rate for fast transient response.
• Delivers low distortion performance with 0.05% differential gain error and 0.1° differential phase error into a 150 Ω load.
• Offers flexible power operation on single or dual supplies with outputs swinging to within 1.3 V of the rails.
• Integrates robust drive capability with 30 mA output current and internal short-circuit protection.

Applications

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

Procurement Notes

Verify the specific JN suffix indicates the 8-lead Plastic DIP package and commercial temperature range. Confirm that the part number matches the exact pinout and specifications required for the target design. Check for obsolescence status as older components may have limited availability. Ensure ESD precautions are observed during handling due to sensitivity.

Selection Notes

Select this component when cost-sensitive video applications require high bandwidth and low distortion. It is suitable for driving back-terminated 150 Ω loads directly. Consider the PDIP-8 package constraints regarding thermal dissipation and board space compared to surface mount options. Verify that the single-supply operation meets the system's voltage requirements.

Part Context

The AD8072JNZ belongs to the AD8072/AD8073 family of low-cost, dual and triple video amplifiers. These devices are designed for high-volume, cost-sensitive electronics requiring solid video performance. The AD8072 variant specifically contains two independent amplifiers in one package, sharing common power pins while maintaining separate inputs and outputs for gain setting flexibility.

Replacement Considerations

The AD8072JR serves as a direct functional equivalent using an 8-Lead SOIC package instead of the PDIP-8 format. Both share identical electrical characteristics and pinouts. Designers must account for the physical footprint differences when substituting between these package types.
