| FFF Compatibility | Shares the exact same SOIC-8 footprint, pinout assignments (including the VL and VH limiting pins on 5 and 8), and physical mounting characteristics.Matches the standard SOIC-8 package dimensions (3.90 mm body width) and surface-mount package form.Meets or exceeds all critical parameters, utilizing the same voltage-feedback limiting architecture with high slew rate and gain-of-four stability. | Pinout is 100% compatible, mapping input, output, supply, and clamp control pins to the identical locations.Standard SOIC-8 surface-mount package.Performs the identical voltage-feedback clamping function with closely matched high-speed performance. | ||
 AI Summary | OPA689U by Texas Instruments: High Speed Operational Amplifiers Wideband, High Gain Voltage Limiting Amplifier 8-SOIC. | The OPA699IDR is the direct, next-generation upgrade designed by Texas Instruments to replace the obsolete OPA689 series. It maintains the identical pin configuration and voltage-feedback limiting architecture while offering superior clamping accuracy and higher output current drive. This makes it the highest-confidence drop-in alternative for the obsolete OPA689U.
| The AD8037ARZ is a high-performance second-source alternative from Analog Devices utilizing a similar input-clamping (CLAMPIN) architecture. It offers highly comparable bandwidth and slew rate characteristics with a slightly relaxed stability requirement of G >= +2, allowing it to function seamlessly in OPA689U sockets.

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 Texas Instruments OPA689U 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 Texas Instruments OPA689U are the OPA699IDR (Texas Instruments) and the AD8037ARZ (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 OPA689U 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 OPA689U (Texas Instruments) is a part in the High Speed Operational Amplifiers category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
