What is the input resistance of AN1 and AN2 in TLV320DAC3120?  If not resistive, please provide detail on input impedance vs. frequency.  Thx.

    Hello!

    The input resistance of AIN1 and AIN2 depends if only one or both AINx inputs are routed to the output mixer.

    Typically, if only one AINx input is routed, the impedance will be around 11.2KOhms. However, if both inputs are routed, the effective impedance will down to 5.6KOhms.
