Tool/software:
Hi,
We need to choose the audio amplifier for the customer customization requirements, and they consider to use the Line out 5V RMS@ 100ohm, the load power is about 500mW;
the OPA1688 is not available for our design, so please kindly advise if TI has any other high driving ability audio amplifier for this project, thanks.
Hi Liang,

OPA1621 and OPA1622 may meet the power dissipation requirement, but it really depends on the temperature operating range and IC's power dissipation in the design.
Here is a list of video training in English. There is another site in Chinese in TI website in China,

If you have other questions, please let me know.
Best,
