I am using TPA0211 for new design. I have a problem which a leak sound from a BTL tied speaker during Earphone mode. Sound volum is not so big ,but semms strange. The swicching circuit of SE/nBTE is same as Datasheet. It seems Output impedance of VO- is enough high.
1)Are there any check point or advices?
2) Is there a specification of leakage sound raio between BTL and SE.
* Condition
VDD=4.5V,SP:8ohm,Ear-phone: 16ohm
VSE(Hi)=4.45V,VSE(Lo)=0.05V
