Beschreibung
Zusammenfassung:	A sigma-delta ADC comprising: a first-input-terminal configured to receive a first-high-voltage-analogue-input-signal; a second-input-terminal configured to receive a second-high-voltage-analogue-input-signal; an output-terminal configured to provide an output-digital-signal, wherein the output-digital-signal is representative of the difference between the first-high-voltage-analogue-input-signal and the second-high-voltage-analogue-input-signal. The sigma-delta ADC also includes a feedback-current-block, which comprises: a first-feedback-transistor having a conduction channel; a second-feedback-transistor having a conduction channel; a first-feedback-switch; a second-feedback-switch; a first-feedback-current-source; and a second-feedback-current-source.
