Abstract
In an integrating A/D converter, first and second reference voltage inputs () alternatingly connect through a reference voltage switch () via a first reference resistor (R) to an inverting input () of an integrator (). A comparator () connected downstream of the integrator () compares a test voltage applied to its test voltage input () with a comparator reference voltage applied to its reference voltage input (). This input () is connected to- the output () of the integrator (). A control device () actuates the first reference voltage switch () in a pulsed manner and measures the time intervals between the individual switching processes. An inverter () inverting a measuring voltage (U) and a first heating resistor (R) coupled thermally with a measuring resistor (R), are connected in series between the measuring voltage input () and the output of the first reference voltage switch ().
