PCM1808-Q1: Audio performance at 16kHz/24bit

Part Number: PCM1808-Q1

Hello team,

I have 1 questions.

Please tell me the S / N, group delay and THD + N at 16kHz / 24bit. I want to compare the performance with 48kHz / 24bit.

Best regards,

Makoto

    Hi Makoto-san,

    These parameters are not fully characterized over sample rate, but based on typical lab measurements you can expect the SNR and THD+N to degrade by about 3.5dB compared to the 48kHz case specified in the datasheet.

    The decimation filter used is the same so the group delay is still 17.4/fs, or 1.08ms at 16kHz.

    Best,

    Zak
