AD8013AN

Overview

The AD8013AN is a low power, single supply, triple video amplifier manufactured by Analog Devices Inc. It features three current feedback amplifiers in one package, optimized for driving back-terminated video loads of 150 Ω each. The device operates on single +4.2 V to +13 V or dual ±2.1 V to ±6.5 V supplies with a maximum quiescent current of 4 mA per amplifier. Key electrical parameters include a 140 MHz unity gain bandwidth (±5 V), 1000 V/µs slew rate, and 18 ns settling time to 0.1%. It offers excellent video specifications such as 0.02% differential gain error and 0.06° differential phase error at G = +2.

Feature Summary

• Integrates three independent video amplifiers within a single package for space-efficient designs.
• Capable of driving large capacitive loads while maintaining rapid settling times without oscillation.
• Features high-speed disable functionality allowing individual channel power-down or high-impedance states.
• Provides output voltage swing to within 1 V of either supply rail for easy signal accommodation.

Applications

• LCD Displays
• Video Line Driver
• Broadcast and Professional Video
• Computer Video Plug-In Boards
• RGB Amplifier in Component Systems

Procurement Notes

Verify the specific ordering suffix 'AN' corresponds to the 14-Pin Plastic DIP package when sourcing replacements. Confirm that the required operating temperature range matches the industrial specification of –40°C to +85°C. Ensure the application circuit accounts for the internal power dissipation limits associated with the plastic encapsulation under maximum load conditions.

Selection Notes

Select this component for applications requiring multiple high-speed video channels with low power consumption. It is suitable for designs needing precise gain flatness and minimal differential gain/phase errors. Consider the 14-pin DIP package if through-hole mounting is required. Evaluate the need for the high-speed disable feature if multiplexing or channel switching is part of the system architecture.

Part Context

The AD8013 belongs to the Analog Devices video amplifier family, specifically designed for professional broadcast and consumer video electronics. It utilizes a proprietary enhancement of the conventional current feedback architecture to achieve wide bandwidth and low distortion. The AD8013AN variant specifically denotes the 14-lead plastic DIP package option within this series.

Replacement Considerations

Direct substitutes include other parts from the AD8013 series such as the AD8013AR-14 (SOIC package) or AD8013ACHIPS (Die form). Verify pin compatibility and package dimensions when transitioning between DIP and SOIC variants.

FAQ

How does the AD8013 handle large capacitive loads?

The AD8013 can drive large capacitive loads without oscillation due to its high open-loop transresistance and low inverting input bias current. Using appropriate feedback resistors increases phase margin, and adding a small output series resistor further improves pulse response.

What is the function of the Disable pins?

Pulling a Disable pin approximately 1.6 V above the negative supply puts the corresponding amplifier into a powered-down state with high impedance output. This allows for channel switching in multiplexer applications or power saving.

What are the typical differential gain and phase errors?

At a gain of +2 and a load of 150 Ω, the AD8013 typically exhibits a differential gain error of 0.02% and a differential phase error of 0.06°, making it suitable for high-fidelity video applications.
