鬼佬“SENDELER”却认为不用LPF,直接电容及电阻就OK!原文如下,电容选值4-8UF
The AK4396 will sound it's best running direct out through the coupling cap without the analog ultra sonic filter. The ultra sonic noise spectrum of this chip is unique in the industry in not needing one. Adding the 1k resistor to the output impedance of the chip tends to choke the sound. Just take the signal out through the blocking cap from one leg as you have shown in the second drawing for 2.8v and omit the filter. No output R or cap to ground. Leave the other leg open, or terminate with a blocking cap and resistor to ground which approximates the load the the + leg will see..
当然后面也争论不断为这个直接输出。 |
