Can the ACS754 family be applied to both DC and AC currents?
The ACS754 family uses Hall effect technology, which is compatible with electrical currents having both DC and AC components. As the datasheet states, the bandwidth of the ACS754 is 35 kHz typical. There is usually a phase lag of at least 45º on the output for AC currents at frequencies exceeding 35 kHz. For transient current signals, the response time can be expected to be ≈10 µs.
