TAS5805M: Does TAS5805 Support 16kHz, 16bit I2S Input

Hi Sirs,

We see harmonic distortion with the TAS5805 with 16bit I2S with 16kHz sample rate, while there is no problem with 32kHz, 44.1kHz, 48kHz, 88.2kHz, and 96kHz sample rates. Does this device support 16kHz sample rate? Customer is going to use PBTL mode in this case.

Distortion with 16kHz sample rate

Normal with 32kHz~96kHz sample rates
