10 / 44 page TLE4998C General Data Sheet 10 Rev 1.0, 2008-12 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. 2.3 Principle of Operation • 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 and stable magnetic offset • 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 |
