Part Number: PCM5100A-Q1 In the datasheet, there are references to "VCOM mode" and "VREF mode." Could you please explain in what usage scenarios or operating conditions these modes are intended to be used? 8.3 Recommended Operating Conditions AVDD Analog…
Part Number: PCM5100A Other Parts Discussed in Thread: TAD5112 We have got the DAC running at 200kHz. However, we have a 8.2kHz requirement.
1) For 8.2kHz rate we are planning to generate 1,049,600Hz System Clock (SCK) and we want to use the external…
Part Number: PCM5100A-Q1 Hello,
I am working with Mr Kenji Ishihara, and we confirmed the followings;
<Status when issue occurs>
* Confirmed I2S correct.
* Confirmed MUTE off correct.
* Confirmed Power on correct.
<How to return to correct…
Part Number: PCM5100A-Q1 Other Parts Discussed in Thread: PCM5101A Hello.I have asked some questions in the past about PCM5101A. We have an irregularly occuring problem, where occasionally no sound comes out from OUTL or OUTR pins. Condition fs: 16.447kHz…
Part Number: PCM5100A Tool/software: Hello, TI team
I saw that the PCM5100A specification sheet stated that the SNR could reach 100dB, but in my project, the actual test failed to achieve this value.I tried to optimize the power supply by adding LDO…
Part Number: PCM5100A-Q1 Could you please confirm whether my understanding is correct that the minimum VDD operating voltage for this DAC is the value specified in the Electrical Characteristics section?
Since a different minimum voltage value is listed…
Part Number: PCM5100A Other Parts Discussed in Thread: TPA3138D2 , Tool/software: Hello, My customer is using PCM5100A and TPA3138D2 for their board and observing some distortion at the maximum volume. As a workaround, they plan to put some attenuation…
Part Number: PCM5100A-Q1 Hi,
We have an issue where the DAC does not transmit analog audio signals even though the I2S signals are input appropriately. This occurs about 1 in 2000 times of power-on.
We have observed that the internal charge pump is…
