AD818AR

Overview

The AD818AR is a low-cost, low-power video operational amplifier manufactured by Analog Devices Inc. in an 8-lead SOIC package. It features a 130 MHz bandwidth at 3 dB with a gain of +2 and a 500 V/µs slew rate. The device operates on single (+5 V) or dual (±5 V to ±15 V) supplies with a maximum supply current of 7.5 mA. Key electrical parameters include a 2 mV maximum input offset voltage, 6.6 µA input bias current, and a minimum output drive capability of 50 mA.

Feature Summary

• Optimized for high-speed video applications requiring gains equal to or greater than +2 or -1
• Capable of driving back-terminated cables with high output current
• Supports flexible power supply configurations including single +5 V operation

Applications

• Video cameras and professional video equipment
• CATV systems
• Color copiers and image scanners
• Fax machines

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your design constraints. Cross-reference the part number with the latest datasheet revision to confirm pinout and electrical characteristics match your system requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring high output drive capability and low power consumption in video signal paths. It is suitable for applications needing excellent differential gain and phase error performance. Consider the 8-lead SOIC package for surface-mount assembly needs. Verify that the required gain configuration aligns with the amplifier's optimized performance range.

Part Context

The AD818 series includes variants such as the AD818AN in an 8-lead PDIP package and tape-and-reel options like the AD818AR-REEL7. These variations share identical core electrical specifications but differ in packaging and shipping formats. The AD818AR specifically denotes the standard small outline package version intended for automated surface-mount manufacturing processes.

Replacement Considerations

The AD818AN serves as a direct pin-compatible replacement offering the same electrical performance in an 8-lead plastic DIP package.
