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: PCM1802 Other Parts Discussed in Thread: PCM1803A ,
Hi,
Are there any concerns if replacing PCM1803A with PCM1802? Is my understanding correct that FSYNC pin should be pulled-up to VDD with the slave mode(FMT1=0, FMT0=0, MODE1=0 and MODE0=0…
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…
Part Number: PCM1803A Other Parts Discussed in Thread: PCM1795 , PCM1808 , PCM1807 Hi,
The power-on-reset sequence is mentioned on page 10 of PCM1803A data sheet as follows. However, it isn't mentioned the relationship between VCC and VDD at power-on and…

The ADC i used PCM1803A,recently i find the group delay of PCM1803A is too high,my boss give me another choice:AK5720
Does TI have another better…
Part Number: PCM1803A Other Parts Discussed in Thread: PCM1808 , PCM1803 Team, I found that there is no PCM1803A EVM on ti.com. Is there any alternative EVM that we can test PCM1803A? Thanks.
Part Number: PCM1803A Team,
Customer is evaluating PCM1803A and found abnormal THD+N and SNR value. AUX input is divided by 22k/24k to get around 1/2 attenuation. When input the 1V/1kHz tone, the measured SNR is only 90dB and THD+N is 0.07%, which is much…
Hello Scott-san,
Thank you for your sample rate 16 kHz operation testing. The customer will use PCM1803A for monitoring a 60 Hz AC line. Of cause, we know an industrial ADC is better than PCM1803A for the application. The reason why they want to use PCM1803A…
