Hi TI,
I use TLV320ADC3101 develop project now, below is my schematic:
I2S mode, MCLK=12.288M fs=48k BCLK=1.536M, 16 bits
My register configuration is as follows:
I2CWRITE(I2C_ADC31, 0, 0X0);
I2CWRITE(I2C_ADC31…

I need to digitize multiple analog consumer-level single-ended line-outs into one merged I2S stream. The DSP mode of TLV320ADC3101 and its configurable I2C address seems…
Good morning,
we are using above mentioned ADC3101 for measuring very low-voltage analog signals. While it does indeed work very well, I'm struggling with the calculation of the overall sensitivity on a theoretical basis…
For I2S the DUTTLV320ADC3101 will generate with 1 bit offset, for the TDM, does it also transmit the I2S data protocol? Is there 1 bit offset for TDM?
And are left justified mode with time-slot-based mode enabled and DSP mode…
We previously have been using the TLV320ADC3101 to monitor differential signals. We now require the device to monitor a single ended signal.
We did a measurement of the noise levels…
Hi all,
There is an information about mixing ADC inputs at pages 28 and 29 of the datasheet, but I've not found any aditional information or specific register for how to providing this feature.
