Package

For this part  "TPA6132A2RTET",  I foud that this package is WQFN on TI website, but it had already been modified ,because this package was "QFN" before. So, I would like to know what the correct package is ?   How to differentiate between "WQFN" and "QFN" ??

Besides, Could you please explain the difference for  "WQFN" and "QFN" ?

您好，这是TI有关封装的具体介绍 www.ti.com/.../type.html

里面有不同封装的具体信息和不同之处。对于WQFN，请参见 www.ti.com/.../wqfn.html

请问那QFN呢？

QFN stands for Quad Flat Non-lead, WQFN 是QFN的一种封装形式。
