AD8013ARZ-14

Overview

The AD8013ARZ-14 is a low-power, single-supply triple video amplifier manufactured by Analog Devices Inc. It integrates three independent current feedback amplifiers in a 14-pin SOIC package. Each channel provides high-speed performance with a unity gain bandwidth of up to 140 MHz and a slew rate of 1000 V/µs. The device operates on single supplies from +5 V to +13 V or dual supplies up to ±6.5 V, consuming a maximum of 4 mA per amplifier. Key features include excellent video specifications such as 0.02% differential gain error and 0.06° differential phase error at 3.58 MHz, large capacitive load drive capability, and individual high-speed disable functions for power-down or multiplexing applications.

Feature Summary

• Integrates three independent high-speed current feedback amplifiers optimized for driving back-terminated video loads.
• Features individual high-speed disable pins per channel to enable power-down modes or high-impedance states for multiplexing.
• Capable of driving large capacitive loads while maintaining rapid settling times without oscillation.
• Delivers precise video signal integrity with minimal differential gain and phase errors across the frequency spectrum.

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required package type, as the source indicates 'AD8013AR-14' corresponds to the 14-pin plastic SOIC. Confirm the temperature range specification aligns with industrial requirements (-40°C to +85°C). Ensure the specific variant requested matches the exact part number designation provided by the manufacturer to avoid discrepancies in pinout or electrical characteristics.

Selection Notes

Select this component when designing circuits requiring multiple synchronized video channels with low power consumption. It is suitable for applications needing high bandwidth and fast settling times, such as professional video equipment or computer video interfaces. Consider its ability to drive capacitive loads if interfacing with long cables or display panels. The integrated disable feature makes it ideal for systems requiring channel switching or power management.

Part Context

The AD8013 series consists of triple video amplifiers designed for high-performance analog signal processing. The AR-14 suffix denotes the 14-pin Small Outline Integrated Circuit (SOIC) package variant within the product line. This family is characterized by its current feedback architecture, which offers wide bandwidth and fast transient response compared to traditional voltage feedback amplifiers.

Replacement Considerations

FAQ

How does the AD8013 handle large capacitive loads?

The AD8013 is capable of driving large capacitive loads while achieving rapid settling times. For optimal performance with significant capacitance, using a small output series resistor along with an appropriate feedback resistor is recommended to maintain stability.

What is the function of the Disable pins?

Each amplifier has a dedicated Disable pin. Pulling this pin high relative to the negative supply puts the amplifier into a powered-down state with high output impedance, allowing for channel switching in multiplexer configurations or reducing power consumption.

What are the typical differential gain and phase errors?

At a frequency of 3.58 MHz with a gain of +2 and a 150 Ω load, the typical differential gain error is 0.02% and the differential phase error is 0.06°, making it suitable for broadcast and professional video applications.
