Hi everyone
I want to use the CS5490 energy measurement IC to measure current using the shunt resistor approach.
Can anyone help me understand the following:
In the datasheet, they write: "The voltage reference between the VREF+/- pins is 2.4V." Hence I was thinking that the full-scale range would be 2.4V.
But at the same time they write: "The full-scale signal level for the current channel is ±50mV and ±250mV for 50x and 10x gain settings, respectively."?
What I don't understand is why they write ±50mV and ±250mV and not ±40mV and ±240mV?
