AD8072JN

Overview

The AD8072JN is a dual, low-cost current feedback video amplifier manufactured by Analog Devices Inc. It operates within a commercial temperature range of 0°C to 70°C and is housed in an 8-lead plastic DIP package. The device delivers high-speed performance with a 100 MHz –3 dB bandwidth at a gain of +2, a 500 V/µs slew rate, and a fast 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.

Feature Summary

• Provides solid video specifications including 0.1 dB gain flatness to 10 MHz and minimal differential gain and phase errors for accurate signal reproduction.
• Features high output drive capability with 30 mA output current and rapid recovery from positive and negative overdrive conditions.
• Operates efficiently on a single 5 V supply with output swing reaching within 1.3 V of the rails.

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 JN confirms the 8-lead Plastic DIP (N-8) package and commercial temperature range. Confirm that the required voltage and current specifications align with the datasheet limits. Ensure proper ESD precautions are observed during handling due to the sensitivity of the internal circuitry.

Selection Notes

Select this component for cost-sensitive applications requiring high-volume production. It is suitable where small size is not the primary constraint compared to the AD8073 triple amplifier variant. Verify that the PCB layout allows for adequate ground planes and bypassing to maintain specified high-speed performance characteristics.

Part Context

The AD8072 belongs to a family of low-cost current feedback amplifiers designed for business and consumer video electronics. It offers accessible inputs and outputs for flexible gain setting. The dual configuration provides two independent amplifiers in a single package, optimizing board space for multi-channel video processing tasks.

Replacement Considerations

The AD8072JR serves as a pin-compatible surface mount alternative in an 8-lead SOIC package. For applications requiring three amplifiers, the AD8073 series provides a triple configuration in 14-lead packages.
