ADS1278: Silicon chip design in ADS1278 Commercial vs ADS1278-SP

Jamie Albin

Part Number: ADS1278

Hi TI team,

I am collecting radiation data for a NASA mission that might use some version of ADS1278. There is a European Space Agency (ESA) test report on the commercial version of ADS1278 from 2014 on Single Event Effects, but I'm not sure those tests results would apply to the space grade version ADS1278-SP. (Note: I do also see lots of test results on ADS1278-SP)

1. Do the commercial versions of ADS1278 have the same internal silicon die as ADS1278-SP? (meaning same internal doping geometries, etc.) I need this info to know whether the 2014 ESA test report applies to our ADS1278-SP part selection.

2. Has TI made any significant chip design changes in either version (commercial ADS1278 or ADS1278-SP) since 2014?

Hello Jamie,

Please give me until end of business this Friday to confirm. I am not certain, but I think the dies have the exact same geometries.

Hello Jamie,

I am still waiting for updates regarding die differences between the -SP and commercial versions of ADS1278. I can confirm there have been no significant die changes since 2014 for the commercial version nor any changes to the -SP version after it released in 2018.

I will provide an update to you regarding the die differences by end of business on Thursday, April 18.

Regards,
Keith

Hello Jamie,

We were finally able to track down the information. There are no differences in geometries of the die, including doping, between the commercial and space rated devices.

Apologies this took so long.

Regards,
Keith
