Abstract
A versatile detection circuit is optimized for low sensor voltages and contains a microprocessor. The microprocessor contains an integrated analog-to-digital converter with an input pin. The integrated analog-to-digital converter is configured to rely on a reference voltage of no more than 2 volts. The detection circuit also has a transformation circuit for transforming a sensor signal, the transformation circuit being connected to the input pin of the integrated analog-to-digital converter. The transformation circuit contains an impedance converter and with the exception of the impedance converter relies only on passive electric elements.
