Abstract: A signal processing circuit includes a first current sensor input, a second current sensor input, a voltage sensor input for receiving a sensor voltage, a first selection unit, a second selection unit, a current analog-digital converter (ADC), a voltage ADC, digital processing block, and a current-voltage converter. The first selection unit includes a first current input coupled to the first current sensor input, and a second current input coupled to the second current sensor input. The second selection unit includes a first voltage input coupled to the voltage sensor input and a second voltage input. The current ADC is coupled to a first current output. The voltage ADC is coupled to a voltage output. The digital processing block is coupled to outputs of the current ADC and the voltage ADC. The current-voltage converter is coupled between a second current output and the second voltage input.
