For each of the techniques, what is the latest and greatest part that can be used? For the core-based solution, the ACS70310 is a solution that gets the best out of the concentrator, reaching a 2.5 times better signal-to-noise ratio (SNR) than the competitors. This is due to the 1% sensitivity and 5mV offset error from 25°C to 150°C that it typically gets thanks to a factory-programmed segmented linear temperature compensation (TC). However, the accuracy can always be affected by the hysteresis of the core, which is why there is need for a careful core design. This technique allows it to have great performance even if the alignment of the sensor is not perfect. For the coreless-based solution, the ACS37612 is a great solution to sense high currents on a notched busbar. It is half of the cost usually needed for these solutions. It is much smaller than the core-based solution, and provides great performance thanks to a differential composition that reduces its sensitivity to stray fields. It also features a 1% typical sensitivity and only 3mV offset typical thanks to the low-drift reached with the factory-programmed segmented linear temperature compensation.
