As the description states, I have this chip designed in, but I am not getting any signs of life from it on pin 12.
My clock signals as ~3v3 in amplitude, and are being driven by a USB <…
Part Number: PCM1803A Hi Team, Do we have the dynamic range characteristics of PCM1803A for no A-Weighting conditions? If available, do we also have the above information for sampling frequency around 20kHz? Kind Regards, Jejomar
Part Number: PCM1803A Hello,
It is not clear which of REF1/2 is for L/R channel. Is REF1 for L channel as the diagram in top page of datasheet implies?
Thanks!

Hello Carson. Sorry for the late reply. It is assumed that the product equipped with the PCM1803A is turned off and then turned on again immedeately. It would be nice if we could control the product and start it up after the power of the PCM1803A was turned…
Part Number: PCM1803A Hi team,
The datasheet of PCM1803A have HPF which cutoff frequency is 0.019*fs. Do you have detail information such that graph, schematic or anything?
Gain and phase at low frequency is important for our project.
Best regards, Koyo …
Part Number: PCM1803A Now I cant' reach Dynamic range 103dB at our design.
Only 100dB I can get.
If possible, I'd know the circuit design method or the board design method for increasing Dynamic range performance.
That means I want to reduce…
Part Number: PCM1803A The 8,17 to 20 pin inputs are fixed to HIgh or Low. If low is selected, can it be grounded directly to GND? If high is selected, can I connect directly to Vcc? If No, please advise the appropriate pull-up and pull-down resistance values…
Part Number: PCM1803A Other Parts Discussed in Thread: OPA2353 Hi,
I want to add a second order LPF with a buffer in front of a PCM1803A.
I'm planning to use the single supply OPA2353. It will run on the same 5V power source as the ADC.
Can I use…
