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.
