AD5546

在使用AD5546做精密衰减的参考电路中,有一个反馈电容C6。这个电容值的大小应该如何随频率变化呢?

在参考输入是正弦波频率是150KHZ~1750KHZ频段的时候适合用多大容值的电容呢?

  • Hi.

          I am also evaluating this DAC for outputs 36 KHz Sine wave. I am using this in four quadrant mode with ADR03 reference in line with data sheet. I have conversion frequency of 1152 KHz. So 32 samples per cycle. But its harmonics performance is poor, just 30 dBc. Why it is so? Should there be any harmonic present??
