... Nearly zero magnetic hysteresis Package: 5 pin module (suffix PFF) 1 Additional leadforms available for qualifying volumes Application 1. The ACS756 outputs an analog signal, V varies linearly with the uni- or bi-directional primary sensed current, I noise management, with values that depend on the application. ACS756-DS ...

... The thickness of the copper conductor allows survival of the device 5× overcurrent conditions. The terminals of the conductive path are electrically isolated from the sensor leads (pins 1 through 3). This allows the ACS756 family of sensors to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques. ...

... ACS756 3 kVRMS Voltage Isolation and a Low-Resistance Current Conductor Definitions of Accuracy Characteristics Sensitivity (Sens). The change in sensor output in response change through the primary conductor. The sensitivity is the product of the magnetic circuit sensitivity ( and the linear IC amplifier gain (mV/G). The linear IC amplifier gain is pro- grammed at the factory to optimize the sensitivity (mV/A) for the half-scale current of the device ...

... ACS756 3 kVRMS Voltage Isolation and a Low-Resistance Current Conductor Definitions of Dynamic Response Characteristics Power-On Time (t ). When the supply is ramped to its operat- PO ing voltage, the device requires a finite time to power its internal components before responding to an input magnetic field. Power-On Time defined as the time it takes for the output PO voltage to settle within ± ...
