The ACS722 and ACS723 Hall-effect current sensor ICs from Allegro MicroSystems Europe are now available in a high-isolation SOIC16 package. The low-profile surface-mount package is ideal for space constrained applications while also saving costs due to reduced board area, yet provides a 4800V RMS isolation rating: the highest available from Allegro’s family of surface-mount current sensor ICs.
The new high-accuracy devices provide economical and precise solutions for AC or DC current sensing in industrial and commercial applications. In addition to their small size and high accuracy, the ACS722 and ACS723 offer the additional benefits of superior isolation performance, low power consumption, and a wide operating temperature range with near zero magnetic hysteresis.
Each device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die.
