TDA4VM-Q1: What's the difference between TDA4VM-Q1 and TDA4VM?

Hi TI engineer，

What is the difference between TDA4VM-Q1 and TDA4VM? The descriptions of both chip are the same, but the prices are different. How do we choose?

Looking forward to your reply. Thank you.

两者的区别是TDA4VM-Q1是汽车级的，符合 AEC-Q100 标准（以 Q1 结尾的器件型号），请看数据手册表 10-1. Nomenclature Description (continued)https://www.ti.com.cn/cn/lit/ds/symlink/tda4vm-q1.pdf
