The ACS755SCB-200 is an economical and precise current sensor from Allegro that provides solutions for current sensing in industrial, automotive, commercial and other applications. It features a single +5 V supply, 3 kVRMS isolation voltage, 35 kHz bandwidth, end-of-line factory-trimmed gain and offset, ultra-low power loss and extremely stable output offset voltage.
The Allegro ACS755SCB-200 current sensor provides precise, low‑offset Hall‑effect measurement for industrial and automotive applications. It operates from a single +5 V supply, offers 3 kV isolation between the primary conductor pins and the sensor pins, and delivers a ratiometric output proportional to the sensed current.
Key features include a 35 kHz bandwidth, ultra‑low internal resistance (≈100 µΩ), factory‑trimmed gain and offset, and a compact package that supports both straight and formed‑signal pin configurations. The device is lead‑free, RoHS‑compliant, and fully calibrated before shipment.
