CSA-1V

August 2004

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

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.
