Availability of DAC900

Amit,

There are no plans to EOL (end of life) the DAC900.  Products like the DAC900 are used in long production run industrial applications and aren't subject to the fast ramp up/down of products built for consumer markets.  As a general explanation of TI's policy on product longevity, the company does not obsolete a product out of convenience.  So long as we can manufacturer it and someone is buying it, it should remain in production.  With that said, no supplier anywhere can guarantee with 100% certainty that they will be able to continue manufacturing a product for a fixed number of years (with some possible exceptions with regards to certain military grade components as an example where special terms may be applied).  Sometimes wafer processes or packages or other key parts of the supply chain out of the control of the supplier become obsolete and the supplier has to react to that.  

TI's obsolescence policy is (if a part needs to be moved to Obsolescence): 

(I've copy/pasted it)

Product Obsolescence Policy: We are also committed to provide notification of Product Obsolescence and offer a Life Time Buy (LTB) opportunity, where applicable. TI allows up the 12 months for an order to be place from the date of notification and allows an additional 6 months to take delivery of the ordered product.

TI will provide the following information:

• Detailed Description
• PCN Tracking Number
• TI Contact Information
• Last Order Date (12 months after notification)
• Last Delivery Date (+6 month after order period ends)
• Product Identification (affected products)
• Identification of Replacement product, if applicable
