AD828AR

Overview

The AD828AR is a dual, low-power video operational amplifier housed in an 8-lead Plastic Small Outline Integrated Circuit (SOIC) package. It features a gain bandwidth of up to 130 MHz at a gain of +2 and a slew rate reaching 450 V/µs. The device operates with supply voltages ranging from ±2.5 V to ±18 V or a single +5 V to +36 V source. Key electrical characteristics include a maximum quiescent current of 15 mA per amplifier, an input offset voltage of 2 mV, and a minimum output drive capability of 50 mA. It exhibits excellent differential gain and phase errors of 0.01% and 0.05 degrees respectively, ensuring high-fidelity signal processing for demanding video applications.

Feature Summary

• Optimized for high-speed video applications requiring gains of +2 or greater with superior differential gain and phase error performance.
• Capable of driving back-terminated cables and heavy resistive loads with a minimum output current of 50 mA per amplifier.
• Supports flexible power supply configurations including single +5 V operation and dual supplies from ±5 V to ±15 V.
• Designed for power-sensitive environments such as video cameras and professional equipment due to low quiescent current consumption.

Applications

• Video monitors and CATV systems
• Color copiers and image scanners
• Fax machines and high-speed transmission circuits
• Professional video equipment and test instruments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. The AD828AR denotes the standard 8-lead SOIC variant; ensure compatibility with existing PCB footprints. Confirm temperature range requirements match the -40°C to +85°C industrial specification. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Always consult the latest datasheet revision for any updates to absolute maximum ratings or recommended operating conditions prior to final design approval.

Selection Notes

Select the AD828AR when application demands include high output drive capability combined with low power consumption. It is suitable for designs requiring operation from a single +5 V supply or dual rails up to ±15 V. Consider this component for video line drivers where maintaining signal integrity over terminated cables is critical. Ensure feedback resistors are kept below 1 kΩ to minimize stray capacitance effects. Verify that the required settling time and bandwidth align with the specified dynamic performance metrics under the intended load conditions.

Part Context
