TPA6166A2: Headset impedance measurement

Part Number: TPA6166A2

Hi team, 

Just want to confirm about whether TPA6166A2 is able to know the impedance of the headset. Customer would like to use this feature to adjust the volume of sound. Please advised. Thanks!

Best Regards,

Leroy Song 

  • HI Leroy,

    This device is detecting the impedance of the load to distinguish between headphone and line-out, but I don't think there is an automatic volume change feature.
