13   These devices combine a high-side current sense amplifier with a 12 bit ADC.
14   They have an i2c interface.

27      Value in micro Ohms of the shunt resistor connected between the RS+ and
28      RS- inputs, across which the current is measured.  Value needed to compute
29      the scaling of the measured current.
