Other Parts Discussed in Thread: LMP92066

Hi all.

I am looking for the 12bit DAC integrated EEPROM.

So if TI has such a device, please tell me it.

Best Regards,

Sho,

We do not have any DACs with an integrated EEPROM. For my own curiosity, can you elaborate on your requirements for such a product and what the application is?

Hi Kevin san.

Thank you for the reply.
I understood you do not have any DACs with an integrated EEPROM.

Sorry, I do not have the information of our customer's application.
I can show you the block diagram.

This device's feature is
・12-bit Resolution
・On-Board Non-Volatile Memory(EEPROM)
・Single supply Operation:2.7V~5.5V
・I2C Interface

Best Regards,
Sho Ogane

Sho,

Are you asking if we have a functional TI replacement for the Microchip MCP4725? I don't believe that we have a similar part.

Sho,

After a little more digging there is actually a somewhat similar device in the TI portfolio called the LMP92066. I'm not intimately familiar with this part or exactly how your customer intends on using it, but it's something for you all to consider.

Question: how big is the EEPROM?

Mark,

This one is from the SVA guys. If it's not in the datasheet I don't have any idea. Not sure how closely those guys watch the forum to know if they will respond to this existing thread. You might try making a new post or emailing Chuck Sins, he's been my go-to guy for mapping who owns what in SVA.

Mark,

It's in the datasheet. If you look at figure 30, it gives an overview on what the registers are used for. In the descriptions afterward, 40h to 6Bh are used for specific settings while 6Ch to 7Fh can be used for arbitrary storage (20 bytes).

Hi Kevin,

There is 20 bytes of user storage in addition to the look-up table in EEPROM.
