Hi,
I'm using a custom board with the DAC PCM4104. I followed the design recommendation of the data sheet. The DAC is active and can be programmed successfully via SPI.
I created a sinus with 16 Bit, two's complement. It is transmitted via I²S with the correct clocks but the output is a square signal. The complete positive half period is 2.5V + 1V and the negative is 2.5V - 1V.
Have you any idea what could cause this error?
Best regards
Roland
