TLV320AIC3106: how to interface single ended line to the TLV320AIC3106 differential inputs correctly ?

Hi there,

searching the web for this question is more confusing then anything. How is that done correctly with the TLV320AIC3106 inputs ?

The cheapest way of course.

Thank you

Best wishes

    Hi, Ralph,

    There are two ways to connect the single-ended line to the TLV320AIC3106.

    - Connect the single-ended line directly to the MIC3R/MIC3L single-ended inputs.
    - In case of differential input (for example, differential inputs LINE1LP and LINE1LM), connect the single-ended line to the positive differential input (LINE1LP). Then, connect the negative differential input (LINE1LM) to a capacitor (0.47uF capacitor suggested) to ground.

    Best regards,
