Allegro MicroSystems ACS723
the ACS723 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 BW_SEL pin can be used to select one of the two bandwidths to optimize the noise performance. 8 MCO-0000538 1 IP+ 8 VCC +I P ACS723 2 IP+ 7 VIOUT IP 3 IP– 6 BW_SEL –IP CL 4 IP– GND 5 Typical Application CBYPASS 0.1 µF The ACS723 outputs an analog signal, VIOUT , that changes, proportionally, with the bidirectional AC or DC primary sensed current, IP , within the specified measurement range.| Part No. | ACS723 |

FEATURES AND BENEFITS
● 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 = 2.4 kVrms □ Basic Isolation Working Voltage = 420 Vpk / 297 Vrms
● Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
● Pin-selectable bandwidth: 80 kHz for high bandwidth applications or 20 kHz for low-noise performance
● 0.65 mΩ primary conductor resistance for low power loss and high inrush current withstand capability
● Small footprint, low-profile SOIC8 package suitable for space-constrained applications
● Integrated shield virtually eliminates capacitive coupling from current conductor to die, greatly suppressing output noise due to high dv/dt transients
● 4.5 to 5.5 V, single supply operation
● Output voltage proportional to AC or DC current
● Factory-trimmed sensitivity and quiescen...
