0012 description: |
0013 These devices combine a high-side current sense amplifier with a 12 bit ADC.
0014 They have an i2c interface.

0027 Value in micro Ohms of the shunt resistor connected between the RS+ and
0028 RS- inputs, across which the current is measured. Value needed to compute
0029 the scaling of the measured current.
