TPA6166A2: Question of Detection Range of OMTP/CTIA Jacks and I2C Code Review of the TPA6166 Amplifier

Hi Sirs,

We are designing the TPA6166 with an OEM customer. Here we have two questions which need product line's support:

1. WOuld you please advise if the TPA6166 detect OMTP and CTIA jacks based on the same impedance range of the TS3A227E device?

TPA6166 datasheet:


 

TS3A227E specification:



2. Can we bring up the TPA6166 to support OMTP/CTIA jack detection function with the following I2C instructions?
