Abstract

A Hall sensor circuit includes a first Hall element and a second Hall element, first and second Analog-to-Digital Converter (“ADC”) channel inputs passively coupled to first and second output nodes of the first Hall element, third and fourth ADC channel inputs passively coupled to the first and second output nodes of the second Hall element, a first ADC output for providing a first digital output signal, and a second ADC output for providing a second digital output signal. The Hall element outputs can be directly coupled to the ADC or coupled through a passive resistor-capacitor filter.
