Adam-san,
Thank you for you kind support.
"Why do you want to use the audio jack above? "
→Customer is limited to the available parts.
Available parts are 4 pin jacks or reported 5 pin jack.
Sorry, I have one more thing to ask.
Customer is trying to use a 4 pin jack and a comparator for TS3A227E.
Use the following comparator to control the DET_TRIGGER pin.
datasheets.maximintegrated.com/.../MAX9060-MAX9064.pdf
Could tell me if you have a case using a comparator?
Also, please tell me the cautions to control the DET_TRIGGER pin with the comparator.
Best Regards,
Yusuke/Japan Disty
