Hi,
I am currently checking the performance for TLV320AIC34 codec ADC, datasheet spec written if single-ended signal, should get 0dBFS with 0.707Vrms input. I configured the MIC3L path with 0dB mixer and PGA gain, noticed that DAI output already reach 0dBFS just with 0.66Vrms. I am using UPV for analog signal generator and DAI signal analyzer, any idea why I can get the value same as datasheet?
Thanks and regards,
Zoe
