AD8013ANZ

Overview

The AD8013ANZ is a low-power, single-supply triple video amplifier manufactured by Analog Devices Inc. It integrates three independent current feedback amplifiers within a single package, optimized for driving back-terminated video loads of 150 Ω. The device operates on single +5 V to +13 V or dual ±2.1 V to ±6.5 V power supplies with a maximum quiescent current of 4 mA per amplifier. Key performance metrics include a unity gain bandwidth of 140 MHz at ±5 V, a slew rate of 1000 V/µs, and a fast settling time of 18 ns to 0.1%. It features excellent video specifications such as 0.02% differential gain error and 0.06° differential phase error. Each channel includes a high-speed disable function with a turn-off time of 30 ns.

Feature Summary

• Integrates three independent high-speed current feedback amplifiers in one package

• Features individual high-speed disable pins for each channel to reduce power consumption
• Provides output voltage swing to within 1 V of either supply rail

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 against the manufacturer's official documentation to confirm the exact package type and reel configuration. The AD8013ANZ designation corresponds to the 14-pin plastic DIP package. Ensure that the procurement source provides valid traceability and authenticity guarantees consistent with Analog Devices Inc. standards. Confirm that the component meets the specified industrial temperature range requirements for your intended deployment environment.

Selection Notes

Select this component when designing circuits requiring multiple synchronized video channels with minimal board space. It is suitable for applications demanding high bandwidth and low distortion, such as professional broadcast equipment. Consider the current feedback architecture when setting gain resistors, as bandwidth is determined primarily by the feedback resistor value rather than noise gain. Ensure adequate thermal management if operating near maximum junction temperatures.

Part Context

The AD8013 series belongs to Analog Devices' portfolio of high-performance video amplifiers designed for signal processing in visual systems. This specific part number represents the industrial grade variant housed in a 14-pin plastic DIP package. It shares functional characteristics with other members of the family but differs in packaging options like SOIC or die form. The device addresses the need for compact, multi-channel solutions in legacy and modern video infrastructure.

FAQ

How does the disable function operate?

Pulling the Disable pin approximately 1.6 V above the negative supply voltage puts the amplifier into a powered-down state with high impedance output. Leaving the pin floating keeps the amplifier enabled.

What is the recommended load for optimal video performance?

Each amplifier is optimized for driving a back-terminated video load of 150 Ω, which ensures the specified differential gain and phase error performance.

Can the AD8013 drive capacitive loads directly?

Yes, it can drive large capacitive loads without oscillation. Using a small output series resistor along with an appropriate feedback resistor is recommended for stable operation with significant capacitance.
