Hi,
Detection error has occurred in the customer's circuit.
Could you tell me about detect CTIA and OMTP?
The following contents are described in the data sheet.
”This is done by directly connecting the microphone bias and the ground connections to the sleeve and ring2 pins of the audio jack. For the end user this leaves a headset standard as fully unsupported.”
However, There is no description of the discrimination method between CTIA and OMTP.
How does TS3A227E distinguish between CTIA and OMTP?
Please tell me about the detection internal circuit.
Detection error occurs in the customer's application when the insertion / removal test is repeated plural times.
Therefore, please explain what kind of method and what TS3A227E is detecting (voltage / current / resistor).
And Should customers process MUTE etc. at the time of insertion / removal?
Best Regards,
Yusuke/Japan Disty
