Image of Allegro's ACS726 Current Sensor The Allegro fully-integrated current sensor IC package allows for easy implementation. The fully-differential output of this device gives better immunity to output offset drift as well as common mode noise.

ACS726 is the first current sensor to include a fully-differential back-end amplifier that can be used to adjust gain and bandwidth via external RC networks. The back-end amplifier is fully independent and when unused, it can be powered down to reduce power consumption.

Features and Benefits
Fully-differential architecture for immunity to output offset drift and common mode noise Spare differential back-end amplifier for externally adjustable gain and bandwidth using simple RC networks High-bandwidth 120 kHz analog output 1.1 mΩ primary conductor resistance for low power loss and high inrush current withstanding capability Small footprint, low-profile QSOP24 package suitable for space-constrained applications		Integrated shield virtually eliminates capacitive coupling from current conductor to die due to high dV/dt voltage transients 3 V to 3.6 V, single-supply operation Factory-trimmed sensitivity and quiescent output voltage for improved accuracy Chopper stabilization results in extremely stable quiescent output voltage Nearly-zero magnetic hysteresis Ratiometric output supply voltage
Applications
Motor control Load detection and management		Switched-mode power supplies Overcurrent fault protection
