本帖最後由 kevin2233 於 2014-10-3 11:00 編輯DIYDAC! 我諗要加 cap. 穩定電壓 試下在 DAC +volt supply 串入 47uH inductor 及 0.1uf cap decoupling ...... {:1_253:} 加cap加在那裡?在牛之前嗎? kevin2233 發表於 2014-10-4 10:48 static/image/common/back.gif
加cap加在那裡?在牛之前嗎?
choke is placed on the V_digital path to DAC,and 0.1uf cap next to the chip.
furthermore, 在牛之前 be installed with X2 caps (MKP) to overcome emi susceptibility .Haven't u ? 咁似我個case..... 師兄係咪玩CAS cd to dac
