Dear Support team,

Please tell me about ADC and DAC of the following devices.

    Masumoto-san,

    I will look into the AIC3106 this is a more recent design and we should have this data on hand. 

    Regarding the others... These devices are quite old (released 2000-2005 or so) the design teams are long gone and design files archived, I will see if I can find some information but i can't guarantee that I will be able to. With devices this old, we may not be able to easily find the information. The devices remain active to support customers who support legacy designs, I would recommend using one of our more recent codecs for new designs. 


    best regards,

    Matsumoto-san,

    I found the following plot for the AIC1103,  which is very closely related to the AIC1106.  I continue to search for the others.  I expect an answer on the AIC3106 shortly

    best regards,

    Wilson-san,

    Thank you for your response.
    It is an older device, but thanks for providing relevant data.

    I will tell this content to my customers.

    Total group delay of TLV320AIC3106 has found the numerical value described in the data sheet.
     - ADC Filter group delay : 17/fs (s)
     - DAC Filter group delay : 21/fs (s)

    I recommend the use of TLV320AIC3104 or TLV320AIC3105 of a new device series to my customers.

    Best regards,

    Hiroaki Masumoto

    Thank you Masumoto-san,

    I think the TLV320AIC310x series is a very good choice.
