Replacement verdict
Compatible functional replacement candidate
The AD812AR and AD812AR-REEL are functionally identical, as the -REEL suffix only denotes tape-and-reel packaging for automated assembly. Both parts share the same die, package, and electrical specifications, making them fully interchangeable in design and production. The only practical distinction is the shipping format, which affects inventory handling rather than circuit performance.

Frequently asked questions
What is the difference between AD812AR and AD812AR-REEL?
The AD812AR and AD812AR-REEL are the same AD812 device in the same 8-lead SOIC package; the "-REEL" suffix denotes tape-and-reel packaging for automated assembly, while the base AD812AR is typically supplied in tube or tray packaging. Electrical performance is identical.
Are the AD812AR and AD812AR-REEL electrically identical?
Yes. Both parts use the same AD812 die and are specified to the same datasheet parameters, including dual-channel current-feedback operation, 145 MHz bandwidth (G = +2), and 1600 V/µs slew rate. The only difference is the shipping packaging.
What package do the AD812AR and AD812AR-REEL use?
Both are offered in an 8-lead SOIC (Small Outline Integrated Circuit) package, commonly designated as the R-8 or SOIC-8 package in Analog Devices documentation.
Can AD812AR and AD812AR-REEL be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable. The choice between them depends on the assembly method: AD812AR-REEL is intended for pick-and-place reel-fed production, while AD812AR is suited to tube-fed or low-volume assembly.
What is the AD812AR-REEL tape-and-reel quantity?
The AD812AR-REEL is supplied on a standard 13-inch reel. The exact reel quantity should be confirmed against the current Analog Devices datasheet or distributor listing, as packaging quantities can vary by orderable part number revision.
What are the key specifications common to both AD812AR and AD812AR-REEL?
Both are dual current-feedback operational amplifiers with 145 MHz bandwidth at G = +2, 1600 V/µs slew rate, and operation on ±5 V to ±15 V dual supplies. They are specified for the industrial temperature range and are used in video, imaging, and high-speed signal processing applications.
Do AD812AR and AD812AR-REEL carry the same moisture sensitivity and handling requirements?
Yes. Because both use the same 8-lead SOIC package and the same die, they share the same moisture sensitivity level and handling precautions. The applicable MSL rating should be verified from the current Analog Devices datasheet or the distributor's product page.
