PCM1681: DAC output is 1V signal

Part Number: PCM1681


Hi,

I'm trying to use the PCM1681 in 24-bit TDM I2S mode.  I have verified that my BCK and system clock that's being given to the PCM1681 is running at 11.2MHz for 44.1 kHz sampling.  I have also verified that there's valid data entering DATA1.  The output that we are seeing from the oscilloscope is a 1V signal.  We don't observe any analog output.  We have also verified that the mute is grounded.  Any pointers into what else to look for?

Thanks,

Tim
