Built-in Amplifier Allows Externally Adjustable Gain

Electrical Review Logo

The new ACS726 from Allegro MicroSystems Europe is a current sensor IC designed to provide an economical and precise solution for AC current sensing in industrial, commercial and communications applications.  

In addition to featuring galvanic isolation, it is the first current sensor IC 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, can be powered down to reduce power consumption. The fully differential output of this device gives better immunity to output offset drift as well as common-mode noise.

The low-profile device package makes it easy to incorporate into customers’ applications. Typical uses for the ACS726 include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.
