Claim 13:
14. The sigma-delta ADC of claim 13 further comprising:
one or more first further feedback resistors arranged in parallel with the feedback resistor, each of the feedback resistor and one or more first further feedback resistors having a first terminal coupled to the filter output; and a plurality of switches configured to switchably couple one of a first voltage and a second voltage to a respective second terminal of the feedback resistor and the one or more first further feedback resistors dependent on the counter output value; and
one or more second further feedback resistors arranged in parallel with the further feedback resistor, each of the further feedback resistor and the one or more second further feedback resistors having a first terminal coupled to the filter further output; and a plurality of further switches configured to switchably couple one of the first voltage and the second voltage to a respective second terminal of the further feedback resistor and the one or more second further feedback resistors dependent on the counter output value.
