各位大侠，我按照DAC161s997的规格书设计好了电路图，单片机没有进行任何的控制，直接调试纯硬件电路，我外接一个10欧的电阻，发现环路电流是24mA，这个是正常的吗？请各位大侠帮帮忙，小弟非常感谢。
这个值应该跟上电默认值有关. 从手册看:
Table 4. DACCODE ddress = 0x04; Default = 0x2400, 0xE800, 那么就不应该有这么大电流, 又
Note the default value of this register is based on the state of the ERR_LVL pin during startup or reset.
留意一下这个条件.
