ACS758xCB
Features and Benefits (continued)
Thermally Enhanced, Fully Integrated, Hall Effect-Based
Linear Current Sensor IC with 100 μ Ω Current Conductor
Description (continued)
? 3.0 to 5.5 V, single supply operation
? 120 kHz typical bandwidth
? 3 μ s output rise time in response to step input current
? Output voltage proportional to AC or DC currents
? Factory-trimmed for accuracy
? Extremely stable output offset voltage
? Nearly zero magnetic hysteresis
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.
