Part Number: TS5A23157
Hope you are doing well.
This is Akshay Pathak working as a Embedded Hardware Engineer in Teksun Microsys Pvt Ltd.
We evaluated one audio application in which we used "TS5A23157" Analog Switch.
Thanks & Regards
Akshay, What type of audio are you switching? Are you switching analog audio centered at 0 V? Are you switching digital audio like I2S or SPDIF? Did you like the performance of the TS5A23157 in your evaluation? Are there any issues you are observing that are prompting your questions. If your audio signal is centered and you need to pass a negative voltage you will need to use a device like the TS5A2236X family. e2e.ti.com/.../421997 The charge injection is typically not an issue in audio systems because customers mute their systems during the switching.
Sorry didn't mean to hit the resolved button yet. (habit) Thank you, Adam

Nice to E-Meet with you.
Q: What type of audio are you switching? Are you switching analog audio centered at 0 V? Are you switching digital audio like I2S or SPDIF?
A: So basically we want to evaluate basic audio application by using of TI analog switch IC (Part no: TS5A23157) which have an R(ON) resistance 10ohm.In that, we want to disturb the audio signal of headphone speakers as well as a mic. so we implement this analog switch between headphone and mobile.
So my point is if I use this analog switch (Part no: TS5A23157) IC which have 10 ohm R(ON) resistance. So While switching audio signal in ON to OFF and again ON condition so 10ohm R(ON) resistance is effected on an audio signal? As per my knowledge, 3 to 8 ohm R(ON) resistance will not effect on an actual audio signal after switching. So I am correct or not? If I am in wrong way so kindly correct me.
Kindly let me know if you need more information for it.

Thanks for your valuable inputs, I appreciated it.
Here I connect the analog switch in series with headphone speakers and mic and they have approx bellow 25ohm impedance. So if I take your suggested part(TS5A22362 ), So what you think 0.79ohm on resistance is suitable for them in series with <25ohm speakers or mic of headphones. After switching I can get a normal output of switch? i mean after switching there will not distortion arrive in an actual audio signal of headphone?
