General Description
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.

FEATUREs:
• Sensitive to a magnetic field parallel to the chip surface
• Very high sensitivity
• Linear output voltage proportional to a magnetic field
• Wide-band: DC to 100kHz
• Very low offset and offset-drift
• Very low noise
• Isolated from current conductor
• Surface mount SOIC-8 package

APPLICATIONs:
• AC and/or DC current measurement
• Wide-Band Magnetic Field Measurement
• Battery Chargers
• AC-DC Converters
• Motor Control
