Sentron Linear 1-Axis Hall IC, CSA-1VG 
Tabs
 
The Sentron CSA-1VG is a single-axis Hall-effect magnetic field 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 an Integrated Magnetic Concentrator (IMC) 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 mounted onto a printed circuit board over the trace that is carrying the current to be measured. Mounting the current sensor in this way offers high voltage isolation from the current carrying conductor. Other geometries are possible for measuring current in cables or bus bars. Please see the Engineering Kits.

The CSA-1VG-SO is RoHS compliant.
