MAX5531，为什么手册说电源VDD电流是6uA，但是可以输出mA级的电流？

手册说明：这里我理解说的6uA是指输出不带载场景吗？就是DAC输出悬空状态？The MAX5530/MAX5531 are single, 12-bit, ultra-low-power, voltage-output, digital-to-analog converters(DACs) offering Rail-to-Rail buffered voltage outputs.The DACs operate from a 1.8V to 5.5V supply and con-sume less than 6A, making them desirable for low-power and low-voltage applications. 在手册的第三页，有这样一段描述：Short-Circuit Current (Note 6) 测试条件：VDD = 1.8V, VOUT set to full scale, OUTshorted to GND, source current最大14mA这个规格是指在输出带最大载能力？
