When i want to diy a HI-FI blutooth headphone amp , there is a CSR8675 module on my desk .
Yes , it can support LDAC and APTX-HD , that's good !
Than i make it , with a CS43198 , 22.5792/24.576 MHZ low jitter OSC , five low noise LDOs , and a NE5532 amp output .
When the phone workwith LDAC output , i have to select 96KHZ sampling rate on the amp , because there is not ASRC work , so the amp must work a same sampling rate with the phone .
The output phase can be select , I like the negative phase , has someone tried it ?
