Hello Team

The SNR of TPA3245 is 112dB. How can get this data use TPA3245EVM? Does single end input can get it? if yes, how do set up it?  the input amplitude?

    Xiao,

    The setup is very important. Do you have an Audio Precision to take the measurement?

    In our lab we measure SNR with respect to DNR using the AP, AUX-0025 filter, and A-Weighting filter.

    We use XLR outputs from the AP for a balanced connection in DIFF mode to the EVM in BTL.

    Regards,
