Abstract
A device for determining a fluid mass flow includes a sensor element for acquiring the fluid, the sensor element being configured within a flow path of the fluid to provide a sensor signal, an integrated circuit having an operating unit for providing an operating signal for operating the sensor element and a conversion unit for converting the sensor signal into a converted signal, the integrated circuit including a first discrete circuit element having a first terminal for receiving the sensor signal, a second terminal for providing the operating signal, and a third terminal for providing the converted signal, and a signal processing unit to determine, using the converted signal, the mass flow of the fluid, the signal processing unit including a second discrete circuit element having a first terminal for receiving the converted signal and a second terminal for providing a mass flow signal representing the mass flow.
