Hi Sirs,
Would you pls advise if the noise floor measurement in line with the PCM2912A's specification? I added AES127 software filter and 10kOhm load impedance
Played 0dB FS, 1kHz sinewave with maximum volume, Got 685.8mV rms (-3.275dBV) as full scale output voltage.
Play silence file, Got 42.76uV (-87.867dBV) as PCM2912AEVM's noise floor. The noise level is audible -> Was it in line with PCM2912A's specification?
Stop playing media file, Got 24.07uV (-93.836dBV) as PCM2912A EVM's shutdown mode.
