General Description
The CSA-1V is a single-axis integrated magnetic field sensor based on the Hall effect. It produces a
linear, ratio-metric output voltage proportional to the applied magnetic field parallel with the chip
surface. The circuit is fabricated using a standard CMOS process. The additional ferromagnetic layer
(IMC-Hall^®) that is added in a simple post-processing step, amplifies the magnetic field and
concentrates it on the Hall elements. 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 and suitable
for up to 600V isolation voltage between the sensor and a conductor on PCB.
