|---|---|---|---|---|
| FFF Compatibility | The package, pin count, and exact pinout assignments (including the Offset Null pins on 1 and 8) are identical to the original AD818AR.Both parts are housed in the standard 8-SOIC (Narrow Body, 3.90mm width) package with identical physical dimensions.Every electrical parameter, including the 130 MHz bandwidth, 500 V/µs slew rate, and ±18V maximum supply voltage, is identical. | Pins 1 and 8 are No Connect (NC) instead of Offset Null pins as on the AD818AR. Fits directly if offset null functionality is not used.Shares the same 8-SOIC package footprint and standard mounting dimensions.Exceeds original bandwidth (220 MHz vs 130 MHz) and output current (145 mA vs 50 mA) while supporting similar wide supply voltages. | ||
 AI Summary | AD818AR by Analog Devices: Video Amp 1 Voltage Feedback 8-SOIC. | The AD818ARZ is the direct RoHS-compliant, lead-free replacement for the obsolete AD818AR, providing identical electrical parameters and physical drop-in compatibility. It remains in an active lifecycle status.
| The ISL55001IBZ is a high-performance, high-voltage operational amplifier that serves as an excellent second-source alternative if the offset nulling capability on Pins 1 and 8 is not actively used in the design.

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 AD818AR 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 AD818AR are the AD818ARZ (Analog Devices Inc.) and the ISL55001IBZ (Renesas Electronics Corporation), 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 AD818AR 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 AD818AR (Analog Devices) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
