ACS756
Description (continued)
Fully Integrated, Hall Effect-Based Linear Current Sensor IC
with 3 kVRMS Voltage Isolation and a Low-Resistance Current Conductor
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.
Selection Guide
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.
