Hello dear support team,
Could you please help me in answering the following questions:
- How big is the input impedance of the INA240
- Are Ref1 and Ref2 real Resistors? Which value do they have (there is no value in the datasheet)?
- How is the PWM filter implemented (e.g. Cut-off frequency)?
- Can it be compared with a standard EMI filter, but with bigger time constant to lower the cutoff frequency?
- Can there be any problems, when the reference voltage can only source?
