Description

This is the compact version of a simple carrier for Allegro’s ACS37030LLZATR-040B3 electrically isolated current sensor that uses two signal paths—Hall effect and inductive coil—to capture both low-frequency and high-frequency information. This allows for a DC through 5 MHz bandwidth and typical response times of 40 ns.
