Hi,
Customer wants to detect audio jack insertion with the following configuration.
■4pin earphone jack "TIP pin"⇒Comparator IN / Comparator OUT⇒TS3A227E DET TRIGER pin
Customer's available earphonejack is a 4 pin product.
For this reason, there is no switch for detecting jack insertion in the jack itself.
I got the following question from the customer.
・Is there a problem by connecting the earphone jack tip pin directly to the input of the comparator?
・Could you tell me the recommended comparator.
Device image is below.

I look forward to hearing from you.
