Will the attached sketch do what is described here:

'...... bias each input with a voltage divider (e.g. 2x 25k) between 3.3V to GND.
This terminates the 11 µA current output and delivers 437 mVpeak (by 12.5 kOhm). As the level does not undershoot 1V, I think it's not a problem for the sensor's output.'


Noticed the pic cut off the left side of the sketch. I have my sin+ and sin- inputs there.

Added a sketch in the post above of what I think the guy is describing.

That's not how I would interpret the words into a circuit diagram.

Can you link to the original post? I can't find it.

That in the sketch is not what he is describing. It says to have 2 resistors in series between +3.3V and GND, use the middle of them as input/output.
Do that for both inputs ( total 4 resistors ).
I did not do the math, but it should be ok.

Yup, that should do it.

And yep; you are correct! The circuit as show above is working fine.

Thanks for the help people.
