ADA2200 is EOL. Substitutes?

Hi,

I and my wife Mariko are developers of GPLv2 open source $300 Real Time PCR "Ninja qPCR" using ADA2200 (GitHub / Youtube / 3dmodel / LatestUpdates ).

We have been developing it over a year and finally sensed diluted fluorescent solution equal concentration to the early stage of COVID-19 detection protocol successfully.

We are preparing final test using synthetic gene of unique DNA sequence of COVID-19 and today, I received a notification of ADA2200 EOL. No substitutes are listed except pricy AD630.

Do you have plan to release substitutes of ADA2200 or no other choice is available forever? I really wish AD keep making such a great chip.

Thank you

Shingo

  • Dear Shingo,

    Consider contacting Rochester Electronics. They sell, and often manufacture under licence, ICs discontinued by the original producers.

    At the moment they have ADA2200 on sale:

    www.rocelec.com/.../ANAADA2200ARUZ-REEL7

    Ask them what they plan for future availability and price of this part.

    The only potential problem can be the minimum order quantity of 47 parts,

    especially if you expect people to built the setup and purchase components themselves.

    In the longer term, you can consider implementing lock-in detection on a

    Texas Instruments MSP430I2021 microcontroller.
