Low-noise analog signal path  
Device bandwidth is set via the new FILTER pin  
5 µs output rise time in response to step input current  
50 kHz bandwidth  
Total output error 1.5% at TA= 25°C, and 4% at –40°C to 85°C  
Small footprint, low-profile SOIC8 package  
1.2 mΩ internal conductor resistance  
2.1 kVRMS minimum isolation voltage from pins 1-4 to pins 5-8  
5.0 V, single supply operation  
66 to 185 mV/A output sensitivity  
Output voltage proportional to AC or DC currents  
Factory-trimmed for accuracy  
Extremely stable output offset voltage  
Nearly zero magnetic hysteresis  
Ratiometric output from supply voltage  
The device consists of a precise, low-offset, linear Hall  
sensor circuit with a copper conduction path located near the  
surface of the die.Applied current flowing through this copper  
conduction path generates a magnetic field which is sensed  
by the integrated Hall IC and converted into a proportional  
voltage. Device accuracy is optimized through the close  
proximity of the magnetic signal to the Hall transducer. A  
precise, proportional voltage is provided by the low-offset,  
chopper-stabilized BiCMOS Hall IC, which is programmed  
for accuracy after packaging.  
Package: 8 pin SOIC (suffix LC)  
The output of the device has a positive slope (>VIOUT(Q)  
)
when an increasing current flows through the primary copper  
conduction path (from pins 1 and 2, to pins 3 and 4), which  
is the path used for current sensing. The internal resistance of  
this conductive path is 1.2 mΩ typical, providing low power

Application 1. The ACS712 outputs an analog signal, VOUT  
that varies linearly with the uni- or bi-directional AC or DC  
primary sensed current, IP, within the range specified. CF  
is recommended for noise management, with values that  
depend on the application.
