What are the differences between the –100, –075, and –050 versions of the ACS750?
The ACS750xCA-075 and the ACS750xCA-100 are physically the same part, but they are tested using different test programs. The sensitivity of both devices is ~20 mV per ampere. Both devices share the same specifications at 25ºC, but certain parameters, such as linearity and accuracy, are itemized to particular temperature ranges on the data sheet. For example, the operating temperature range of the ACS750ECA-100 is de-rated to allow performance through 100 A, and the specifications of the ACS750LCA-075 are guaranteed through the full automotive temperature range of -40ºC to 150ºC. The only difference between those two versions and the –050 version of the device is the sensitivity. For the –050 version, sensitivity is set to ~40 mV per ampere.
