Part Number: TPA6140A2YFFEVM Other Parts Discussed in Thread: TPA6140A2 , TPA6140A2EVM Hi all
My customer has the TPA6140A2YFFEVM and the driver doesnt install properly.
They are on Win 10.
Please comment how to proceed.
Best regards

I also stumbled on the TPA6130A2. This looks like a perfect companion to the PCM5242. Do you agree?
Looks like the TPA6140A2 is also available, but only in WCSP. Are there any major reasons to switch from the TPA6130A2 to the TPA6140A2?
Thanks again, your…

Please help me to find the lowest Supply Current for driving 2X32 Ohm speaker of the headset.
I found the TPA6101A2 looked good…
Hi Shinichi-san, I don't think this data is available. I assume that an FFT (spectrum analysis) on the output of the device with 50ohm loads is what your customer is looking for, right? I could try to perform a test on the device to get some data…
Jia Jia,
For the headphone amp the highest SNR are TPA6140A2/TPA6141A2 (105dB), the next better are TPA6132A2 and TPA6136A2 (100dB).
Regarding the DAC, some of them could be PCM1795/PCM1796/PCM1798 (123dB) or PCM1789 (113dB), I selected these based on…
Mochizuki-san,
Capacitive load is not specified in TPA614x data sheet. Perhaps this was not documented during characterization. However I found an old report of stability on TPA6140A2 that could be helpfull. Please find attached document.

Hi Hasebe-san,
Have you had NI VISA drivers installed before you installed TPA6140A2 software?
Perhaps your system has newer version of NI VISA drivers on your system and the EVM is not able to work with these.
If this is the case, you could try to uninstall…
Hi Uwe,
I would suggest you to take a look to our TPA6130A2, this device shares similar characteristics with the TPA6140A2 and comes in a WQFN package.

Is the SGND pin on TPA6140A2 different from the SGND on the TAP6132A2?
I ask because the TPA6140A2 data sheet seems to indicate SGND should only be connected to the TRS shield ground, and not to the AGND. Am I correct in assuming that SGND connected…
Other Parts Discussed in Thread: TPA6132A2 , TPA6140A2 , TPA6130A2 , TPA6133A2 During shutdown of the headphone amplifier I need to check (by GPIO source and an ADC channel) if loads are present at the ooutputs. Acc to datasheet TPA6132A2 has typical 50 Ohms…
