AD828AR-REEL

Overview

The AD828AR-REEL is a dual, low-power video operational amplifier manufactured by Analog Devices Inc. in an 8-lead SOIC package with tape and reel packaging. It features a 130 MHz -3 dB bandwidth at a gain of +2, a 450 V/µs slew rate, and an 80 ns settling time to 0.01%. The device supports flexible power supplies ranging from a single +5 V to dual ±5 V through ±15 V operation, drawing a maximum supply current of 15 mA. It provides high output drive capability with a minimum output current of 50 mA per amplifier and maintains excellent video performance metrics including 0.01% differential gain error and 0.05° differential phase error.

Feature Summary

• Optimized for high-speed video applications requiring gains of +2 or greater and significant output drive capability.
• Delivers excellent static and dynamic matching characteristics suitable for demanding transmission environments.
• Capable of driving back-terminated cables and capacitive loads up to 10 pF without oscillation.
• Features low power consumption and single-supply functionality ideal for power-sensitive equipment.

Applications

• Video cameras and professional video equipment
• CATV systems and video monitors
• Color copiers, image scanners, and fax machines
• Full-duplex transmission over coaxial cables

Procurement Notes

Verify the specific ordering suffix REEL against the manufacturer's documentation to confirm the 13-inch tape and reel configuration. Ensure the component meets the required operating temperature range of -40°C to +85°C. Confirm that the 8-lead SOIC package dimensions align with the target PCB layout constraints. Cross-reference the datasheet revision C specifications for accurate electrical parameters during integration.

Selection Notes

Select this component when designing circuits that require high output current drive for cable termination alongside low power consumption. It is appropriate for applications needing precise differential gain and phase performance under varying supply voltages. Consider its voltage feedback architecture and input bias current characteristics when determining feedback resistor values to maintain stability and minimize offset errors in high-frequency signal paths.
