Regarding 2-layer PCB Design for ATSAML21
Posted: Tue Oct 16, 2018 4:52 am
Hi Folks,
I am intending to build a flex 2-layer PCB including ATSAML21(WLCSP) as the microcontroller. I chose this microcontroller due to its embedded opamp functionality that I want to take advantage of.
The idea of the project is to build a small size power efficient flexible PCB for quick measurements.
Question: In order to configure the opamp as an instrumentation amplifier or a transimpedance amplifier, I am confused with the schematic design. I would really appreciate some feedback on the schematic I have attached for the same purpose.
Thanks in advance,
Kind Regards,
Saoni
