The IC is produced in BiCMOS technology with high voltage capability, also providing
reverse polarity protection.
Digital signal processing, using a 16-bit DSP architecture together with digital
temperature compensation, guarantees excellent long-time stability as compared to
analog compensation methods.
While the overall resolution is 16 bits, some internal stages work with resolutions up to
20 bits.
The PWM output frequency can be selected within the range of 122 Hz up to 1953 Hz.

• 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/D conversion ensure a very low
• A programmable Low-Pass filter reduces the noise
• The temperature is measured and A/D converted, too
• Temperature compensation is done digitally using a second order function
• Digital processing of output value is based on zero field and sensitivity value
• The output value range can be clamped by digital limiters
• The final output value is transferred in a rectangular, periodic signal with varying duty
• The duty cycle is proportional to the 12-bit output value
