-RFB
+RFB positive sense pin connects to the resistor RFB+ terminal to form the RFB+ Kelvin connection.
-RFB negative sense pin connects to the resistor RFB- terminal to form the RFB- Kelvin connection.
Feedback resistor RFB, negative terminal
GND
Ground pin is capacitively coupled to the internal ESD circuit and should be connected to power supply
common or signal GND. Also connected to the lid.
