The CSA-1V is a single-axis 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 CSA-1V is packaged in a standard SOIC-8 full plastic package. This package provides:
• highest isolation for applications with the current conductor on the PCB
• highest sensitivity for applications with the current lead above the chip. |
