Audio switch

Hello,

 

I would like to use some audio switches for my audio application. As my ADC (the ADAU1761) is having a THD+N of -90dB (0.0031%) for the single-ended input, thus I am looking for audio switches with at least the same quality. They could be SPST or SPDT or dual SPDT or (maybe) quad SPDT but also DPDT or even SP3T switches.

Of course it is also important that they have a low On-resistance, for not generating suplimentary Johnson noise when switched on.

The input signal voltage is between 0,13525 and 2,75 Vp-p.

 

Extra question: What switches should be used when the input signal voltage is up to 17,5Vp-p?

 

I am looking forward for your response!

Thank you in advance.

Teodor
