The ACS722LLCTR-10AB-T is a high-accuracy, galvanically isolated current sensor IC designed for AC or DC current sensing applications. It features a small footprint in an 8-pin SOIC package, making it suitable for space-constrained designs. The device operates within a supply voltage range of 3 to 3.6 V and provides a ratiometric output voltage proportional to the sensed current, with a sensitivity of 132 mV/A. This sensor is capable of measuring bidirectional currents up to ¬±10 A and offers a linearity of ¬±1% and accuracy of ¬±3%. It includes integrated digital temperature compensation for stable performance across a wide temperature range of -40¬8C to 150¬8C. The ACS722 also features pin-selectable bandwidth options of 80 kHz for high-speed applications or 20 kHz for low-noise performance, along with a low primary conductor resistance of 0.65 m,Ѷ, which minimizes power loss. However, it is important to note that the ACS722 has been classified as "Not for New Design," indicating that it is not recommended for new applications due to potential obsolescence. Existing customers may still utilize this part for current applications, but new designs should consider alternative products.
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.
