Hello,
The output of the LDC0851 is nominally VDD - 0.4V in the off state (inductance of LREF > LSENSE) and 0.4V in the on state (LSENSE < LREF). Refer to the VOH and VOL specifications in the electrical characteristics table of the LDC0851. Also note that the abs max voltage on the supply is 3.6V, therefore you should not exceed this voltage or damage to the device can occur.
If you want to translate the output voltage, a simple way could be to connect the output of the LDC0851 to a comparator with a supply voltage of 0V and 30V.

Dear Sir,
Thanks for the input.
If the output is needed to be PNP or NPN open collector.Then can we provide the required???

Dear luke,
we have designed interface LDC0851 .testing the coil design attached coil proxy working for proximity 3mm.indusctance 20 microhenry
We are targeting for 5mm proximity so designed another coil with more number of turns as well as wide tracks as per attached coil167.15 microhenry.
expected inductance with latest coil was more to have more proximity at 5 mm.How it resulted to less inductance as well well as less proximity.
Please guide how to design coil between 16-17 mm OD to have 5mm sensing distance.
dear sir,
We have coil 15uH which is attached ,we tested ok with LDC0851 interface proximity 2.5 mm.
What changes we need to do so that we can achieve 5mm proximity.
