Signal processing circuit and signal processing device

A signal processing circuit includes first and second current sensor inputs (PD1, PD2) that receive respective sensor currents and a voltage sensor input that receives sensor voltages. A first selection unit (SEL1) includes first and second current input terminals coupled to the first and second current sensor input terminals, respectively, and is configured to select one of the first and second current input terminals as a first selected input terminal connected to the first current output terminal, and select one of the first and second current input terminals as a second selected input terminal connected to the second current output terminal. A second selection unit (SEL2) includes a first voltage input coupled to the voltage sensor input (VIN), and a second voltage input, and is configured to connect one of the first and second voltage inputs to the voltage output. A current ADC (IADC) is coupled to the first current output and a voltage ADC (VADC) is coupled to the voltage output. A digital processing bl
