Datasheet Allegro ACS724MA

ACS724KMA
High-Accuracy, Hall-Effect-Based Current Sensor IC
with Common-Mode Field Rejection in High-Isolation SOIC16 Package
DESCRIPTION FEATURES AND BENEFITS • Differential Hall sensing rejects common-mode fields
• Patented integrated digital temperature compensation
circuitry allows for near closed loop accuracy over
temperature in an open loop sensor
• UL60950-1 (ed. 2) certified
□□ Dielectric Strength Voltage = 4.8 kVRMS
□□ Basic Isolation Working Voltage = 1097 VRMS
□□ Reinforced Isolation Working Voltage = 565 VRMS
• Industry-leading noise performance with greatly
improved bandwidth through proprietary amplifier and
filter design techniques
• Filter pin allows user to filter output for improved
resolution at lower bandwidth
• 0.85 mΩ primary conductor resistance for low power
loss and high inrush current withstand capability
• Low-profile SOIC16 package suitable for spaceconstrained applications
• 4.5 to 5.5 V single supply operation
• Output voltage proportional to AC or DC current The Allegro^TM ACS724KMA current sensor IC is an economical
and precise solution for AC or DC current sensing in industrial,
commercial, and communication systems. The small package …
