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.
