Replacement verdict
Compatible functional replacement candidate
The AD8170ARZ and AD8170ARZ-R7 are functionally identical, sharing the same silicon die, package, and electrical specifications; the only distinction is the tape-and-reel packaging format of the -R7 variant. Either part number can be used interchangeably in the same application, with the -R7 option preferred for automated high-volume assembly lines.

Frequently asked questions
What is the difference between AD8170ARZ and AD8170ARZ-R7?
The AD8170ARZ and AD8170ARZ-R7 are the same AD8170 device in the same 8-lead SOIC (R-8) package. The suffix difference is packaging format: AD8170ARZ is the standard tube/rail packaging, while AD8170ARZ-R7 denotes tape-and-reel packaging (7-inch reel) for automated assembly. Electrical and functional specifications are identical.
Are the AD8170ARZ and AD8170ARZ-R7 electrically and functionally identical?
Yes. Both part numbers refer to the same AD8170 die and package; only the shipping/packaging format differs. Datasheet parameters such as supply voltage range, bandwidth, and pinout apply equally to both.
What is the AD8170 and what are its key verified specifications?
The AD8170 is a low-power, high-speed 2:1 multiplexer amplifier from Analog Devices. Verified datasheet specifications include operation on ±5 V or single +5 V supplies, a −3 dB bandwidth of 250 MHz (G = +2), 0.1 dB gain flatness to 70 MHz, and a slew rate of 1000 V/µs. It is offered in an 8-lead SOIC package.
Can AD8170ARZ and AD8170ARZ-R7 be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because they are the same device in the same 8-lead SOIC package. The only practical difference is the delivery format (tube vs. tape-and-reel), which affects assembly handling rather than circuit performance.
Which packaging format should be selected for production?
AD8170ARZ-R7 (tape-and-reel) is typically preferred for automated SMT pick-and-place production lines, while AD8170ARZ (tube/rail) is often used for prototyping, low-volume, or manual assembly. Selection depends on the assembly process, not on device performance.
What supply voltage and power characteristics apply to both variants?
Both variants operate from ±5 V dual supplies or a single +5 V supply, as specified in the AD8170 datasheet. The device is a low-power multiplexer amplifier; consult the manufacturer datasheet for exact quiescent current and power dissipation values under the intended supply configuration.
Do both part numbers share the same pinout and package dimensions?
Yes. Both AD8170ARZ and AD8170ARZ-R7 use the 8-lead SOIC (R-8) package with identical pinout and package dimensions, so the PCB land pattern is the same for either ordering option.
