Hi guys
I would like to ask/confirm if my circuit designs is workable.
I took reference from two designs,
1. MSP430FR2311 Microcontroller IR Reflection Sensing Reference Design(www.ti.com/.../TIDM-FRAM-IRREFLECTIONSENSING)
2. Always-on Low-power Gas Sensing with 10+ Year Coin Cell Battery Life Reference Design(http://www.ti.com/tool/TIDA-00756
Currently, I am trying to implement CC2652R instead of MSP430FR2311. And I need an additional TIA circuitry.
From the reference 1, I do not know which TI Amp do they use as it is internal built in.
So, I followed reference 2, and use the external TIA circuit. Will this work?
Reference 2 uses LPV812. However, should my feedback components be the same? or should i follow reference 1?
Any kind soul please help.
Thank you and hope to hear from you soon.
Regards
Daniel Lim
Hi Paul
Thank you for the information.
I will test out the circuit with reference to the 2nd one.
Cheers
Daniel
