AD813AR-14-REEL7

Overview

The AD813AR-14-REEL7 is a low-power, single-supply triple video amplifier manufactured by Analog Devices. It integrates three current feedback amplifiers in a 14-lead SOIC package, optimized for driving back-terminated video loads of 150 Ω. The device operates on supply voltages ranging from +3 V to ±15 V with a maximum quiescent current of 5.5 mA per amplifier. Key electrical specifications include a unity gain bandwidth of 125 MHz and a slew rate up to 500 V/μs. It features high-speed disable functions for each channel, rail-to-rail output swing capability within 1 V of the rails, and excellent differential gain and phase error performance suitable for broadcast and consumer video electronics.

Feature Summary

• Integrates three independent video amplifiers in a single package for space-constrained designs.
• Features a high-speed disable function per channel to power down or high-impedance outputs.
• Optimized for driving 150 Ω back-terminated video loads with minimal signal distortion.
• Supports single or dual power supplies with wide operating voltage ranges.

Applications

• Video line drivers
• LCD drivers
• Computer video plug-in boards
• RGB amplifiers
• CCD based systems

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the 7-inch reel packaging format required for your automated assembly equipment. Confirm that the AD813A variant meets the necessary industrial temperature range specifications for your operational environment. Ensure compatibility with the 14-lead SOIC footprint during PCB layout verification.

Selection Notes

Select this component when designing portable or battery-powered video systems requiring low power consumption alongside high bandwidth. The current feedback architecture allows for fast settling times and wide bandwidths independent of gain settings. Consider the internal short-circuit protection and high output drive capability when interfacing with heavy capacitive loads or transmission lines.

Part Context

This part belongs to the AD813 family of triple video amplifiers, designed for general-purpose high-speed applications. It is available in various packages including plastic DIP and SOIC, as well as chip form. The series is characterized by its ability to operate efficiently on low voltage supplies while maintaining professional-grade video signal integrity across multiple channels.

Replacement Considerations

Direct substitutes include the AD813AN (DIP package) and AD813ACHIPS (die form). Verify pinout compatibility and thermal dissipation requirements when transitioning between package types such as SOIC and DIP.
