Current Sensor

The CSA1V is a singleaxis integrated magnetic field sensor based on the Hall effect. The circuit is fabricated using a conventional CMOS technology with an additional ferromagnetic layer. The ferromagnetic layer is used as a magnetic flux concentrator providing a high magnetic gain. Therefore, the circuit features very high magnetic sensitivity, low offset, and low noise. The CSA1V is packaged in a standard SOIC8 full plastic package. This package provides:
- highest isolation for applications with the current conductor on the PCB (up to 600V)
- highest sensitivity for applications with the current lead above the chip.

Features
- Sensitive to a magnetic field parallel to the chip surface
- Very high sensitivity ± 7,5 mT
- Linear output voltage proportional to a magnetic field
- Input voltage 5V
- Wideband: DC to 100kHz
- Very low offset and offsetdrift
- Very low noise
- Isolated from current conductor
- Surface mount SOIC8 package
- Temp. range -40°C to 125°C
