[0076] 1、电路上电后,Bin-端处的电压由于是由电阻串联分压组成,故此处的电压恒定。 [0076] 1, the power circuit, since the voltage at the end of Bin- by dividing resistor in series with the composition, so the constant voltage here. Bin+端处的电压是由R3、R12、R7、C5组成,取样R7端处的电压。 Bin + is the voltage at R3, R12, R7, C5 composition, sampling the voltage at the end of R7. 由于电容的充电过程,Bin+处采集的电压是一个缓慢上升过程。 Since the charging process of the capacitor, Bin + voltage is acquired at a slow rising process.
