interface is further described in
pulling the output pin to low only. Therefore, the high level needs to be obtained by an
external pull-up resistor. This output type has the advantage that the receiver may use
an even lower supply voltage (e.g. 3.3 V). In this case the pull-up resistor must be
connected to the given receiver supply.
The IC is produced in BiCMOS technology with high voltage capability, and it also has
reverse-polarity protection.
Digital signal processing using a 16-bit DSP architecture together with digital
temperature compensation guarantee excellent long-time stability compared to analog
compensation methods.
While the overall resolution is 16 bits, some internal stages work with resolutions up to
20 bits.

• A magnetic flux is measured by a Hall-effect cell
• The output signal from the Hall-effect cell is converted from analog to digital
• The chopped Hall-effect cell and continuous-time A/D conversion ensure a very low
• A programmable low-pass filter to reduce 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 represented by the data nibbles of the SPC protocol
