Abstract:
1. An apparatus for optimizing power consumption of an electrical circuit component in an operating- and evaluating-circuit of a two-conductor field device, comprising: a control unit, which switches the electrical circuit component in an active and an inactive phase with a clock signal; an energy supply unit is provided for supplying the electrical circuit component with energy; at least one energy-storing component is connected to at least one output, at least one input, and/or; a supply input of the electrical circuit component; wherein: at least one switching unit is provided in a conductor path between the electrical circuit component and said energy storing component; and said control unit so operates said switching unit, synchronized with clocking of the electrical circuit component, that through interrupting of the conductor path by the switching unit, the charge of the energy-storing component remains during the inactive phase of the circuit component at least partially in place, and no parasitic discharge currents can occur via the circuit component, so that a discharging current of the energy storing component flowing back into the circuit component is minimal.
