AD725ARZ

Overview

The AD725ARZ is a low-cost video encoder manufactured by Analog Devices Inc., designed for encoding three channels of composite video signals. It operates on a single 5 V power supply with a typical current consumption of 30 mA. The device features bandwidths of 4.4 MHz and 5.2 MHz, ensuring signal integrity for standard definition applications. It is housed in a 16-lead SOIC package suitable for surface mount technology. The component supports an operating temperature range from -40°C to +85°C and has a maximum power dissipation of 800 mW.

Feature Summary

• Integrates three independent video encoding channels within a single integrated circuit.
• Operates efficiently using a single 5 V power supply configuration.
• Provides high-frequency signal processing capabilities for composite video standards.

Applications

• Composite video signal encoding systems
• Standard definition video transmission equipment
• Low-cost consumer electronics requiring video interface solutions
