... ACS710 results in exceptional accuracy in both analog and digital output signals. The internal resistance of the copper path used for current sensing is typically 1 mΩ, for low power loss. Also, the current conduction path is electrically isolated from the low voltage Continued on the next page… ...

... Although the device is accurate over the entire linear range, the device is programmed for maximum accuracy over the range defined by I The reason for this is that in many applications, such as motor control, the start-up current of the motor is approximately three times higher than the running current ...
