With reference to datasheet section 6.7 on the typical characteristic of TPA3131D2, may I know if there's any source of information I can get for typical characteristics at 32dB?
Checked on EVM board, the a-weighting noise @32dB is 130uV. And you can calculate the SNR according to a-weighting noise and output power. Actual SNR is correlated with calculation data.
Power efficiency is related to output power, not related to gain setting. So you refer the figure 3, 7 and 11 in datasheet.
