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

• AC and/or DC current measurement
• Wide-Band Magnetic Field
Measurement
• Battery Chargers
• AC-DC Converters
• Motor Control
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.
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 (up to 600V)
• highest sensitivity for applications with the current lead above the chip.
