Datasheet ACS714 (Allegro) - 3

Automotive Grade, Fully Integrated, Hall-Effect-Based Linear Current Sensor IC ACS714 with 2.1 kVRMS Voltage Isolation and Low-Resistance Current Conductor Description (continued)
the conductive path are electrically isolated from the signal leads The leadframe is plated with 100% matte tin, which is compatible (pins 5 through 8). This allows the ACS714 to be used in applications with standard lead (Pb) free printed circuit board assembly processes. requiring electrical isolation without the use of opto-isolators or Internally, the device is Pb-free, except for flip-chip high-temperature other costly isolation techniques. Pb-based solder balls, currently exempt from RoHS. The device is The ACS714 is provided in a small, surface mount SOIC8 package. fully calibrated prior to shipment from the factory.
