Abstract
The invention relates to a circuit for providing isolated data transfer. The circuit comprises a sensor adapted to be coupled to a conversion circuit, the conversion circuit, which is adapted to use a signal generated by the sensor and an offset voltage to generate in a time sequential manner, a first voltage level and a second voltage level, wherein the second voltage level is larger than the first voltage level. The circuit comprises a voltage to current transformer circuit adapted to convert the first voltage level into a first current level within a current range and the second voltage level into a second current level within the current range, wherein the first current level and the second current level are time sequentially provided to an optocoupler. The optocoupler is adapted to receive time sequentially the first current level and the second current level and to provide an isolated output voltage having a first voltage when the first current level is provided to the optocoupler and a second voltage when the second current level is provided to the optocoupler, an analog to digital converter adapted to receive the isolated output voltage and adapted to provide a digital output voltage and a controller coupled to the analog to digital converter, wherein the controller is adapted to derive the signal generated by the sensor from the digital output voltage corresponding to the isolated output voltage received in the time sequential manner.
