conductive path are electrically isolated from the signal leads (pins

1 through 3). This allows the ACS756 family of sensor ICs to be

used in applications requiring electrical isolation without the use of

opto-isolators or other costly isolation techniques.

The device is fully calibrated prior to shipment from the factory.

The ACS75x family is lead (Pb) free. All leads are plated with 100%

matte tin, and there is no Pb inside the package. The heavy gauge

leadframe is made of oxygen-free copper.
