Replacement verdict
Compatible functional replacement candidate
The AD8552AR and AD8552AR-REEL are functionally identical zero-drift operational amplifiers; the only distinction is packaging format, with the REEL variant supplied on tape and reel for automated assembly. Both share the same die, electrical specifications, and SOIC-8 footprint, making them fully interchangeable in design and production contexts.

Frequently asked questions
What is the difference between AD8552AR and AD8552AR-REEL?
The AD8552AR and AD8552AR-REEL are the same AD8552 zero-drift operational amplifier die in the same 8-lead SOIC (R-8) package. The suffix difference refers to packaging format: AD8552AR is supplied in tube/rail form, while AD8552AR-REEL is supplied on tape-and-reel for automated assembly. Electrical specifications are identical.
Are the electrical specifications of AD8552AR and AD8552AR-REEL identical?
Yes. Both orderable part numbers share the same AD8552 datasheet specifications, including typical offset voltage of 1 µV, offset voltage drift of 0.005 µV/°C, rail-to-rail input and output, and a gain bandwidth product of 2 MHz. The reel suffix does not change device performance.
Can AD8552AR and AD8552AR-REEL be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because both are the same AD8552 in the 8-lead SOIC package. The only practical difference is the shipping format, so the choice depends on whether the assembly line uses tube-fed or reel-fed pick-and-place equipment.
What package do AD8552AR and AD8552AR-REEL use?
Both parts are offered in the 8-lead SOIC package (R-8 suffix). The package body, pinout, and PCB land pattern are the same for both orderable part numbers.
Which part number should be ordered for high-volume automated assembly?
AD8552AR-REEL is the appropriate choice for high-volume automated assembly because it is supplied on tape-and-reel, which is compatible with standard pick-and-place feeders. AD8552AR in tube/rail form is typically used for low-volume or manual assembly.
Do AD8552AR and AD8552AR-REEL differ in temperature range or qualification?
No. Both orderable part numbers refer to the same AD8552 device and share the same specified operating temperature range and qualification status as documented in the AD8552 datasheet. The reel suffix denotes packaging only.
Is AD8552AR-REEL a different silicon revision from AD8552AR?
No. The -REEL suffix is a packaging designation, not a silicon revision indicator. Both part numbers refer to the same AD8552 amplifier and should be treated as equivalent devices for design purposes.
