 AI Summary | AD7390AR by Analog Devices: 12 Bit Digital to Analog Converter 1 8-SOIC. | The AD7390ARZ is the direct RoHS-compliant, lead-free replacement for the obsolete AD7390AR. It offers an identical R-2R architecture, SPI interface, and voltage supply range from 2.7V to 5.5V without requiring any PCB or software changes.
| The AD7391ARZ is the 10-bit sibling within the same family, sharing the exact same pin layout and package footprint. While it is fully compatible physically and electrically, it provides a lower resolution of 10 bits instead of 12 bits, which may be acceptable depending on the application's precision requirements.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Analog Devices AD7390AR is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Analog Devices AD7390AR are the AD7390ARZ (Analog Devices Inc.) and the AD7391ARZ (Analog Devices Inc.), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the AD7390AR are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The AD7390AR (Analog Devices) is a part in the Data Acquisition category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
