dac8760我想把电流设置在4~20ma，但是输出电流在8~12ma之间，始终找不出问题，请问哪里出了问题？
代码如下
dac8760_Write(W_ADDR_NOP,0x0000);
dac8760_Write(W_ADDR_CTRL,(1<<12)|V_0_5);
TicksDelayMs( 1, NULL );//
dac8760_Write(W_ADDR_CONFIG,(1<<8)|I_4_20);
TicksDelayMs( 1, NULL );//
dac8760_Write(W_ADDR_GAIN,0x0000);
dac8760_Write(W_ADDR_ZERO,0x0000);
while(1)
{
dac8760_Write(W_ADDR_DATA,0xffff);
IWDT_Clr();
TicksDelayMs( 1000, NULL );//
}
硬件如图
