AD725ARZ-R7

Overview

The AD725ARZ-R7 is a low-cost video encoder manufactured by Analog Devices Inc. It features three independent channels for encoding composite video signals. The device operates on a single 5 V power supply with a typical current consumption of 30 mA. It utilizes a 16-lead SOIC package designed for surface-mount installation. The operational temperature range spans from -40 °C to +85 °C. Key electrical specifications include bandwidths of 4.4 MHz and 5.2 MHz, with a maximum power dissipation of 800 mW.

Feature Summary

• Integrates three distinct channels for simultaneous composite video signal processing
• Designed for cost-effective implementation in standard video encoding applications
• Supports surface-mount technology within a compact 16-lead SOIC footprint

Applications

• Composite video encoding systems
• Video surveillance equipment
• Consumer electronics requiring analog video output

Procurement Notes

Verify the specific suffix against official documentation, as the R7 designation indicates tape-and-reel packaging which may differ from tube-packaged variants. Confirm component availability status directly with the manufacturer or authorized distributors, as discontinuation notices may apply to this product line. Ensure all ordering details match the exact part number required for the design.

Selection Notes

Select this component when a multi-channel composite video encoder is required within a limited budget. Verify that the 5 V single-supply operation aligns with the system power architecture. Ensure the SOIC-16 package dimensions fit the printed circuit board layout constraints. Check if the specified bandwidth parameters meet the signal integrity requirements of the target application.

Part Context

This component belongs to the AD725 series of video integrated circuits produced by Analog Devices. It serves as a specialized solution for converting digital data into composite video formats. The series is characterized by its integration of multiple encoder channels into a single package, facilitating simplified board designs for video-centric devices.

Replacement Considerations

Consult official substitution guides for compatible video encoders. Verify pin compatibility and electrical specifications before replacing existing inventory. Cross-reference datasheets to ensure functional equivalence in the target application.
