OPA4227: Product information related with Lifecycle

Part Number: OPA4227

This is Joong-hyeok Lee, DMSMS researcher of Leoinnovision.
Leoinnovision is the official EOL(End Of-Life)/obsolescence part manager of Korean Military (Army, Navy, Air force) and PLM agency of many defense industries (Hanwha, ADD, etc.)
Especially, your product has been used in developing TACM(Torpedo Acoustic Counter Measure) detecting equipment manufactured by LIG NEX1.
On behalf of Korean DoD(Defense Of Department), we are checking EOL/status information on the parts of system. At the next year, the TACM equipment will be going to operate. Accordingly, Korean DoD hopes to know the information related with product EOL(End Of-Life) to sustain equipment operation.

Part Number: OPA4227UA
Part Application: TACM, Electrical Cabinet(Signal Processing), Receiver, DC Power, CCA(Filter)

In case of part obsolescence, our military and Korean DoD hopes to know the information related with product EOL(End Of-Life).
So could you provide me some information of the item?
I need the data below.

1. Start of Production(Release date/Start of selling Point) : YYYY-MM
2. Discontinued or Not : Y or N
3. End of Production/Expected EOL Point : YYYY-MM(If it was discontinued/will be discontinued or have plan to discontinue)
4. End of Sales : YYYY-MM(If it will be discontinued or have plan to sell)

If the item has not any discontinuance schedule, please let me know.
Korean DoD will use the information above only for the research and the next purchase.

Feel free to contact me if you have any further information of me and my company.

    TI has a portfolio of high-performing devices that have been on sale for many years yet retain a large customer base due to their robust design, such as including the OPA4277 which is known for its extremely low input offset voltage and drift.

    TI's official obsolescence policy can be found here: www.ti.com/.../product_change_notification.page

    Please note that in the event that TI ever does obsolete/EOL a device, in most cases purchasing customers will have the opportunity to Life Time Buy (LTB) the device for 12 months following the obsolescence notification.

    We do not have any expectations to EOL this device anytime soon, and recommend it for new designs. Please let me know if you have any additional questions about any of the devices you have inquired about.
