Hi,
We are considering to decrease the external components since we don't use the headphone amplifier.
Could you please give us your advice about unnecessary external components ?
For example,
- Not apply the power supply for HPVDD
- Not use the decoupling capacitors for HPVDD and HPVSS
- Not use the flying capacitor for CPP and CPN
- Not use the input capacitors for HPL_IN and HPR_IN
Best regards,
Kato
