Part Number: ADS1292R
Other Parts Discussed in Thread: ADS1293

Hi All,

I am currently using ADS1293 in my design And considering ADS1292R for my next iteration. I have below queries about the device. Please clarify. 

1) What is the device availability and production status? 

2) Does this comply with the standards AAMI EC11:1991/(R)2001/(R)2007, AAMI EC38 R2007, EC13:2002/(R)2007, IEC60601-1 ed. 3.0 b:2005, IEC60601-2-25 ed. 2.0 :2011, IEC60601-2-27 ed. 2.0 b:2005, IEC60601-2-51 ed. 1.0 b: 2005. 

3) Is it compatible with dry electrode impedances? 

Regards

Lakshmi

    Hi Lakshmi,

    As per the top right corner on the first page of the datasheet, the ADS1292R was released in December 2011.

    TI does not have any longevity programs or make statements on how long a device's manufacturing lifetime may be. Here is a quote from a document located at www.ti.com/quality It is in the General Quality Guidelines document.

    TI’s Product withdrawal/discontinuance process complies with J-STD-048, latest issue. TI makes an effort to not obsolete products out of convenience. Convenience means: low running device, poor yields, limited customer adoption or similar items. TI’s obsolescence withdrawal schedule provides a longer lead time than the industry standard. TI allows 12 months for the last order and an additional 6 months to take final delivery of obsolete items. In rare circumstances, an accelerated withdrawal schedule may be necessary. In such cases, TI will communicate the last buy and final delivery dates in the EOL notice, along with an explanation of the circumstances necessitating the early withdrawal.

    That being said, I do not see the ADS1292R going NRND anytime soon.

    The standards you've listed are system level standards and as such do not apply to individual devices. That being said, systems have passed these systems using the ADS1292R. 

    Once again this is a system level concern, but the ADS1292R is capable of measuring signals acquired from dry electrodes.
