The device consists of a precise, low-offset, linear Hall circuit
with a copper conduction path located near the surface of the
die. Applied current flowing through this copper conduction

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.

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 sampling. The internal resistance of
this conductive path is 1.2 mΩ typical, providing low power
loss. The thickness of the copper conductor allows survival of

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