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

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