EVM430-FR6043: What is the function of resistor R49? Is it possible not to connect?

Hi Yale,

It is used to match the circuit impendance and need connect. We do not reccomend customer change any circuit parameters and connections with the reference design. Improper cuicuit can cause midpoint drift.

If they find their has some issue with current params, and want design a new circuit to match the impendance of their products, then they should ask thier transducer vendor for help.

B.R.
