Allegro MicroSystems ACS724
the ACS724 current sensor IC to be used in high-side current sense applications without the use of high-side differential amplifiers or other costly isolation techniques. The FILTER pin can be used to decrease the bandwidth in order to optimize the noise performance.

FEATURES AND BENEFITS
● AEC-Q100 qualified● Differential Hall sensing rejects common-mode fields
● 1.2 mΩ primary conductor resistance for low power loss and high inrush current withstand capability
● Integrated shield virtually eliminates capacitive coupling from current conductor to die, greatly suppressing output noise due to high dv/dt transients
● Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
● High-bandwidth 120 kHz analog output for faster response times in control applications
● Filter pin allows user to filter the output for improved resolution at lower bandwidth
● Patented integrated digital temperature compensation circuitry allows for near closed loop accuracy over temperature in an open loop sensor
● Small-footprint, low-profile SOIC8 package suitable for space-constrained applications
● Filter pin simplifies bandwidth limiting for better resolution at lower frequencies Continued on the next p...
