ACHS-7123 Current Sensor Carrier -30A to +30A
This board is a simple carrier of Broadcom’s bidirectional ±30A ACHS-7123 Hall effect-based linear current sensor, which offers a low-resistance (~0.7 mΩ) current path and electrical isolation up to 3 kV RMS. This version accepts a bidirectional current input with a magnitude up to 30 A and outputs a proportional analog voltage (66 mV/A) centered at 2.5 V with a typical error of ±1.5%. It operates from 4.5 V to 5.5 V and is intended for use in 5 V systems.
