Hi Team,

My request to download the PUREPATHCONSOLE tool was unfortunately denied. Could you please let me know why it was rejected, and how I can re-apply or update my information to get approval? I have already purchased the TAS2764 EVM and urgently need the software.

Thank you!

RE: TLV320ADC5120: 我计划用TLV320ADC5120的一个通道接2个DMIC，如何设计

您好

从理论上来看没有问题，但是在匹配和功能实现上建议您仿真测试相对来说比较确实。

我希望用TLV320ADC5120接两个数字DMIC，是接到N2P上还是可以直接接到GP1上，另外其他不用的管脚是否直接接地还是通过电容接地？

TPA3255: TPA3255指标问题

Part Number: TPA3255

TPA3255EVM规格书中标注的315W 10%THD+N 4Ω功率

1、标注条件为至少可持续1秒左右，还是说持续了一段时间的

例如输出315W功率时，失真≤10%，且可持续输出60秒

2、测试条件同理，是第一种还是第二种?

1：输入1kHz正弦波，慢慢增大输入电平，当THD达到10%时，记录此时功率（不关注持续时间，只看能否达到）

2：输出315W功率时，失真≤10%，且可持续输出60秒

你好

在良好的散热条件下，输出功率会持续稳定输出。在某些情况下，设备会因过热或其他警告而关机，测试应尽量避免此类故障或错误发生。

溴，

We do not have approval authority, but according to convention, a TI account registered with the company email is required, otherwise the application is highly likely to be rejected.

PUREPATHSTUDIO: Software Access Inquiry: PurePath Console 2 Request for Personal Non-Commercial Audio Project (PCM5242)

Sam Song — Fri, 19 Jun 2026 03:26:34 GMT

Part Number: PUREPATHSTUDIO

Dear TI Audio Support Team,

I am writing to respectfully request access to the PurePath Console 2 software to develop a custom hardware project based on the PCM5242 DAC chip.

I would like to clarify whether the PurePath software suite is strictly reserved for commercial business entities, or if it can be granted for independent educational and personal use. My project is entirely non-commercial; I am designing a high-performance, portable 4.4mm balanced USB audio dongle for my personal use to upgrade my audio experience.

The PCM5242’s native differential output and architecture make it perfect for my hardware layout, and I would love to use your official development tools for developing and configuring the internal miniDSP features inside the chip as well.

If personal or educational access is permitted, could you please advise on how I can proceed with the approval process given my lack of a corporate email? I am more than happy to share my schematic progress or project details to verify the legitimacy of my request. However, if this software is strictly restricted to commercial users and access is unpermitted for personal projects, that is completely fine as well.

Thank you very much for your time and consideration.

Best regards,
