芯片手册中关于电流采样计算公式：VSOUT = VREF + (RREF * ILOAD) / 4000
其中VREF可否为0，直接接地？
还有手册中电流采样部分这样的描述以及EV6543-L-01A DEMO板中电路是什么意思？
To terminate the outputs when using an A/D converter with inputs that are ratiometric to its supply voltage, use two equal-value resistors to the ADC supply and ground. The resulting ADC code will be half-scale at zero current. Figure 2 shows a simplified drawing of the current measurement circuit.
我的应用case是驱动2804级别的电机，单相电流在0.5A左右，可否用以下电路？
谢谢
