ACS758xCB
Thermally Enhanced, Fully Integrated, Hall Effect-Based
Linear Current Sensor IC with
100
μΩ
Current Conductor
Description (continued)
conductive path are electrically isolated from the signal leads (pins
1 through 3). This allows the ACS758 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 ACS758 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.
