Description
Clearance notice: These older current sensors are on clearance at a discounted price and will be discontinued once remaining component stock is depleted. This board is a simple carrier of Broadcom’s bidirectional ±20A ACHS-7122 Hall effect-based, electrically isolated current sensor, which offers a low-resistance (~0.7 mΩ) current path and electrical isolation. This version accepts a bidirectional current input with a magnitude up to 20 A and outputs a proportional analog voltage (100 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.
