Hi Expert,

My customer ask TI codec for Hi-Res? Would you guide me AIC3xxx serials which can support it? Thanks!

    Hi, Jerry,

    Based on the link that you provided, almost all of our AIC3xxx audio codecs support Hi-Res.

    - The TLV320AIC310x devices support sample rates from 8KHz to 96KHz and 16/20/24/32 Bits Data.
    - The TLV320AIC311x devices support sample rates from 8KHz to 192KHz (separated DAC and ADC sample rates) and 16/20/24/32 Bits Data.
    - The TLV320AIC32xx devices support sample rates from 8KHz to 192KHz and 16/20/24/32 Bits Data.

    Devices from the TLV320AIC32xx family support the best processing blocks (or miniDSP) of all our codec devices.

    Best regards,
    Luis Fernando Rodríguez S.

    Hi Luis,

    But some information shows the the Hi-Res Audio logo must produce a bandwidth of 40kHz. I have checked AIC3xxx codec, the frequency response shows to 20KHz.

    Hi, Jerry,

    Unfortunately, our audio codecs cannot reach a bandwidth of 40KHz. They have an internal filter that limits the output in an audible range (from 20Hz to 20KHz). The Hi-Res sampling rates and the data bits are supported, but this bandwidth cannot be reached by all our audio converters.
