说明：  AD7915/AD7916中文数据手册 AD7915/AD7916是16位、逐次逼近型模数转换器(ADC)，采用单电源VDD供电。 器件内置一个低功耗、高速、16位采样ADC和一个多功能串行接口端口。 在CNV上升沿，AD7915/AD7916对IN+与IN-引脚之间的电压差进行采样， 这两个引脚上的电压摆幅通常在0 V至VREF之间、相位相反。 基准电压(REF)由外部提供，并且可以独立于电源电压(VDD)进行设置。 功耗和吞吐速率呈线性变化关系。
(AD7915/AD7916 Chinese Datasheet AD7915/AD7916 is a 16-bit successive approximation analog to digital converter (ADC), a single power supply VDD. It contains a low power, high speed, 16-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, AD7915/AD7916 voltage difference between IN+ and IN- pin is sampled voltage swing these pins usually between 0 V to VREF, the opposite phase. A reference voltage (REF) is applied externally and can be independent of the supply voltage (VDD) settings. Power and throughput rate scales linearly.)
