The ACS722 is a galvanically isolated, high-accuracy current sensor IC in a small footprint SOIC8 package, designed for AC or DC current sensing in industrial and power applications. It operates from a 3 to 3.6 V single supply with a typical primary conductor resistance of 0.65 mΩ and offers pin-selectable bandwidths of 80 kHz or 20 kHz. The device features integrated digital temperature compensation and an optimized output proportional to current, with UL60950-1 certification for 2.4 kVrms dielectric strength and 420 Vpk basic isolation working voltage. This specific variant, ACS722LLCTR-05AB-T, is a ±5 A sensing model with Pb-based solder bumps, supplied in tape and reel packaging, and operates over the -40°C to 150°C temperature range. The part is classified as not for new design and is no longer recommended for new applications.
The ACS722 provides precise current measurements for AC or DC current, featuring pin-selectable bandwidth (80kHz or 20kHz), galvanic isolation, and a small footprint for space-constrained applications. Operates at 5V.
