Summary: | An electronic circuit (1), in particular for a battery management system, the circuit comprising: at least an input (Vn; Vp), destined to be connected to a voltage source located upstream of the circuit; at least an electronic amplifier (10), provided with at least a positive input terminal (11), a negative input terminal (12) and a voltage output (13) and possibly a voltage reference (Vref), the input being electrically connected to the positive input terminal or the negative input terminal; at least a voltage divider (20) interposed between, and connected with, the at least an input and one from among the positive input terminal and the negative input terminal. The circuit further comprises at least an analog switch (30) operatively connected in series to the at least a voltage divider and selectively operable at least between a closed condition, in which it enables passage of electric current from the at least an input to the electronic amplifier, and an open condition, in which it interrupts passage of electric current from the at least an input to the electronic amplifier. The electronic amplifier is an operational amplifier or and instrumentation amplifier; the analog switch is a bipolar junction transistor (BJT), a field effect transistor (FET) or a relay. |
