TLV320AIC3204 Input Impedance for bypass configuration

Other Parts Discussed in Thread: TLV320AIC3204

Hi,

I am using the TLV320AIC3204.

I can only find information for input impedances concerning the MICPGAs but not for when the bypass configuration is used.

Is there somewhere I can find this information?

Thanks,

Col

    Hello Col,

    I just heard back from the design team. The input impedance for bypass configuration (analog input pin directly to HP amp) is typically 6.6kohms with a +/- 20% tolerance across devices due to process variation. Note that usually this varation is from wafer to wafer and often not found with such large margins within a single device.

    Hope this helps! Please let me know if you need anything else,

    Nate
