TLV320AIC3101芯片输入动态范围为什么达不到最大值0.707v?

Other Parts Discussed in Thread: TLV320AIC3101

TLV320AIC3101输入动态范围0.707VRMS,实际输入0.63VRMS时,最大采样值已到32768,也就是说ADC输入的信号范围只到0.63V,不能到0.707V,如果输入大于0.63VRMS,采集的数据会出现削顶。测试方法:ADC、DAC的增益我全部设成0dB, AVDD_DAC = DRVDD = IOVDD = 3.3 V, DVDD = 1.8 V, 输入信号为48 kHz, 16-bit, 1k正弦波音频信号。
