The Allegro MicroSystems ACS722LLCTR-05AB-T is a galvanically isolated, Hall-effect current sensor IC for bidirectional AC and DC current measurement over a +/-5 A range. It provides a ratiometric analog voltage output with 264 mV/A typical sensitivity at 3.3 V. The device operates from 3.0 to 3.6 V over -40 to +150 degrees C and is supplied in an 8-pin SOIC package. Its bandwidth is pin-selectable between 20 and 80 kHz. The manufacturer identifies the ACS722 as not recommended for new designs; typical applications include existing motor-control, power-supply and load-monitoring systems. The -T construction contains Pb-based solder bumps and meets RoHS through applicable exemptions.
