Sentron Linear 1-Axis Hall IC, CSA-1V
 |
| |
 The Sentron CSA-1V is a single-axis Hall-effect current sensor IC that has been optimized for AC and DC current measurement applications. The current sensor is fabricated using conventional CMOS technology with an additional ferromagnetic layer. The ferromagnetic layer is used as a magnetic flux concentrator to provide a higher magnetic gain than would be normally possible. Therefore, the circuit boasts very high magnetic sensitivity with low offset and noise.
In a typical application, the current sensor is normally mounted onto a printed circuit board just over the trace that is carrying the current to be measured. Mounting the current sensor in this way reduces the errors induced by poor positioning of the sensor with respect to the current conductor and offers high voltage isolation from the current carrying conductor.
The CSA-1VG-SO is RoHS compliant.
