The following is not understandable in LMP8481 DATASHEET 8.1.1 Theory of Operation. Can you explain it? Thank you!
"Internally, the voltage on each input pin is converted to a current by the internal precision thin-film input resistors
RGP and RGN. A second set of much higher value VCM sense resistors between the inputs provide a sample of
the input common-mode voltage for internal use by the differential amplifier.
VSENSE is applied to the differential amplifier through RGP and RGN. These resistors change the input voltage to a
differential current. The differential amplifier then servos the resistor currents through the MOSFETs to maintain
a zero balance across the differential amplifier inputs."
How does MOSFET maintain zero balance on the inputs?
