Hello,
I searched the topics in the forum and i didn't get my answer completely.
I applied 5V to VCC and 3.3V to VDD and followed the schematic presented in the device datasheet. The inputs are ac-coupled audio signals. when i measure VREF1 by multimeter, the voltage value is around zero!! and VREF2 is around 5V. According to the datasheet, i think VREF1 should be 0.5*VCC = 2.5V. Am i right? if yes, what is the problem?
