AD813AR-14-REEL

Overview

The AD813AR-14-REEL is a low-power, single-supply triple video amplifier manufactured by Analog Devices Inc. It integrates three current feedback amplifiers in a 14-lead plastic SOIC package. The device operates on supply voltages ranging from +2.4 V to +36 V or dual supplies up to ±18 V. Key electrical specifications include a unity gain bandwidth of 125 MHz and a slew rate of 500 V/µs. Each channel provides an output current capability of 50 mA and features a high-speed disable function with a turn-off time of 80 ns.

Feature Summary

• Integrates three independent video amplifiers within a single compact package for space-constrained designs.
• Features a high-speed disable function per channel to power down the amplifier or place the output in a high-impedance state.
• Optimized for driving back-terminated video loads with excellent differential gain and phase error performance.
• Operates efficiently on low voltage single supplies while maintaining high-speed signal processing capabilities.

Applications

• Video line driver circuits
• LCD drivers
• Computer video plug-in boards
• Ultrasound imaging systems
• RGB amplifier stages

Procurement Notes

Verify that the specific ordering suffix corresponds to the reel packaging format required for automated assembly processes. Confirm the component meets the industrial temperature range specifications of -40°C to +85°C as defined in the official datasheet. Ensure compatibility with standard surface mount soldering profiles for 14-lead SOIC packages during integration.

Selection Notes

Select this component when a design requires multiple video channels within a limited board area. Consider the current feedback architecture which dictates that bandwidth depends on the feedback resistor value rather than the closed-loop gain. Evaluate the quiescent current consumption against battery life requirements for portable applications utilizing single-supply operation.

Part Context

This part belongs to the AD813 family of triple video amplifiers produced by Analog Devices. It is designed to replace discrete solutions by combining three amplifiers into one unit. The device utilizes a complementary bipolar process to achieve high speed and low power consumption simultaneously, making it suitable for consumer electronics and broadcast equipment.

Replacement Considerations

Check pinout compatibility if substituting with other triple video amplifiers. Verify that alternative components support the required 14-lead SOIC footprint and meet the necessary bandwidth and disable functionality specifications.
