AD813AN

Overview

The AD813AN 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 DIP 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. The input offset voltage is typically 5 mV, and the quiescent current per amplifier is 5.5 mA maximum.

Feature Summary

• Integrates three independent video amplifiers within a single package for space-efficient designs.
• Features a high-speed disable function per channel to power down amplifiers or high-impedance outputs.
• Optimized for driving back-terminated video loads with excellent differential gain and phase error performance.
• Operates efficiently on low single-supply voltages 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 the specific suffix 'AN' corresponds to the 14-lead plastic DIP package and industrial temperature range (-40°C to +85°C). Confirm that the ordering code matches the exact revision required for your design. Check manufacturer documentation for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a compact solution for multiple video channels is required. Ensure the application utilizes current feedback topology compatible with the specified feedback resistor values. Verify that the load impedance and supply voltage align with the device's linear output swing and bandwidth requirements. Consider the disable pin functionality if multiplexing or power management is needed.

Part Context

The AD813 belongs to Analog Devices' family of low-cost, single-supply video amplifiers. It is designed for applications requiring high bandwidth and low power consumption. The device is available in various packages including SOIC and chip form factors, with the AN variant specifically denoting the through-hole DIP configuration suitable for prototyping and general-purpose PCB assembly.

Replacement Considerations

Consult official datasheets for direct replacements such as the AD813AR (SOIC package) or AD813ACHIPS (die form). Cross-reference pinouts and electrical specifications carefully, as package changes may affect thermal dissipation and layout requirements. No other functional substitutes are confirmed in the provided documentation.
