请教关于 DAC8750 供电范围的几点疑问。

Other Parts Discussed in Thread: DAC8750

我现在做4~20mA电流输出。想用DAC8750芯片实现。在看DAC8750的数据手册,发现并没有写DAC8750最低供电范围,只写有“最大环路依从电压: AVDD - 2V“,是不是可以这么理解,假如我用AVDD = 9V,负载RL最大的电压为 9 - 2 = 7V,也就是说,最大带载能力为 7V / 20mA = 350Ω;如果我需要带载250Ω,DAC8750最小AVDD = 250Ω * 20mA + 2 = 7V(理想状态下,不考虑线阻等)?

谢谢了。
