2.3
• A magnetic flux is measured by a Hall-effect cell.
• The output signal from the Hall-effect cell is converted from Analog to Digital signals.
• The chopped Hall-effect cell and continuous-time A to D conversion provide very low
• A programmable Low-Pass filter reduces the noise.
• The temperature is measured and A to D converted.
• Temperature compensation is processed digitally using a second order function.
• Digital processing of output voltage is based on zero field and sensitivity value.
• The output voltage range can be clamped by digital limiters.
• The final output value is D to A converted.
• The output voltage is proportional to the supply voltage (ratiometric DAC).
• An On-Board-Diagnostics (OBD) circuit connects the output to
