Let's take a 1A AC current as an example to explain what the output voltage is, and AC does not need to distinguish the direction of current flow; <br>according to the formula, the <br>output voltage is Vout=VCC/2+Ia*K = VCC/2+ (0.4V*ia) =2.5+0.4; the <br>output voltage range is: 2.9V---2.1V, where Vout can be directly connected to the AD port of the single-chip microcomputer; <br>working temperature: -40 ~ 80 °C
