Description
The Allegro ? ACS711 provides economical and precise
solutions for AC or DC current sensing in <100 V audio,
communications systems, and white goods. The device package
allows for easy implementation by the customer. Typical
applications include circuit protection, current monitoring,
and motor and inverter control.
The device consists of a linear Hall sensor circuit with a copper

Low-noise analog signal path
100 kHz bandwidth
Small footprint, low-profile SOIC8 and QFN packages
3.0 to 5.5 V, single supply operation
Integrated electrostatic shield for output stability
Factory-trimmed for accuracy
Extremely stable output offset voltage
Zero magnetic hysteresis
Ratiometric output from supply voltage
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.
The output of the device has a positive slope proportional to
the current flow from IP+ to IP– (pins 1 and 2, to pins 3 and
4). The internal resistance of this conductive path is 0.6 m Ω
Packages:
for the EX package, and 1.2 m Ω for the LC package, providing
a non-intrusive measurement interface that saves power in
applications that require energy efficiency.
The ACS711 is optimized for low-side current sensing
applications, although the terminals of the conductive path
are electrically isolated from the sensor IC leads, providing
sufficient internal creepage and clearance dimensions for a
8-pin SOICN
with internally fused path

Application 1. TheACS711 outputs an analog signal, V IOUT , that varies linearly with the
bi-directional AC or DC primary current, I P , within the range specified. The ˉFˉ ˉA ˉUˉˉLˉ ˉTˉ pin trips
when I P reaches ±100% of its full-scale current.
