maintainers:

description: |
The LMP92064 is a two channel ADC intended for combined voltage and current
measurements.
The device contains two ADCs to allow simultaneous sampling of voltage and
current and thus of instantaneous power consumption.

description: |
Value of the shunt resistor (in µΩ) connected between INCP and INCN,
across which current is measured. Used to provide correct scaling of the
raw ADC measurement.
