ts12a12511 --USE THIS ONE--.pdf

Dear Technical Support Person,

Inside the data sheet for this analog switch in section 8.3 page #14 states:

8.3

Feature Description The TS12A12511 can pass signals with swings of 0 to 12 V or –6 V to 6. The device is great for applications where the AC signals do not have a common mode voltage since both the positive and negative swing of the signal can be passed through the device with little distortion.

MY QUESTION IS:

Can you please explain what is the common mode voltage being referred to here? Is it a large dc offset? if so how large?

Thanks,

Steve Dunn

Hi Steven,

The common mode is something that would be needed on a device if it only supported single supply.

The common mode voltage for this device refers to the voltage needed (DC bias) to raise your signal swing from going ~6V below 0V .Since this device can pass signals with swings of 0 to 12 V or –6 V to 6, it does not require you to apply a common mode voltage.

Regards
