Datasheet ACS724 (Allegro) - 2

Automotive-Grade, Galvanically Isolated Current Sensor IC ACS724 with Common-Mode Field Rejection in a Small-Footprint SOIC8 Package FEATURES AND BENEFITS (continued) DESCRIPTION (continued)
• 5 V, single supply operation The ACS724 is provided in a small, low-profile surface-mount • Output voltage proportional to AC or DC current SOIC8 package. The leadframe is plated with 100% matte tin, • Factory-trimmed sensitivity and quiescent output voltage for which is compatible with standard lead (Pb) free printed circuit improved accuracy board assembly processes. Internally, the device is Pb-free, except • Chopper stabilization results in extremely stable quiescent for flip-chip high-temperature Pb-based solder balls, currently output voltage exempt from RoHS. The device is fully calibrated prior to shipment • Nearly zero magnetic hysteresis from the factory. • Ratiometric output from supply voltage
