The ACS37003 is a fully integrated current sensor IC designed for precise current measurement in various applications. It features a low-resistance integrated conductor (265 ) for minimal power dissipation and high operating bandwidth (400 kHz) for fast control loops. The sensor offers high accuracy, factory-trimmed for reliability without customer programming. Its internal construction provides high isolation (5 kVRMS) between the primary current path and the signal leads, making it suitable for high-voltage applications with industry-leading basic (1140 VRMS) and reinforced (572 VRMS) working voltages. The device is UL-certified to 62368-1 and is RoHS compliant. It is ideal for applications requiring fast, accurate current sensing with robust isolation.
