TDA7266D13TR Temperature specification related

[skybuble]

Hi ST Team
I have a question about the TDA7266D13TR product.
Checking the TDA7266D13TR datasheet gives the specifications for the TDA7266D and lists the operating temperature as 0°C to 70°C.
The temperature specification I need is -20~85°C or higher.
Please let me know if there are other options based on temperature.

Hi,

> temperature specification I need is -20~85°C or higher

So take some chip with "automotive" characteristics, maybe TDA7377 ;

Thank you for your kindness.

Since we plan to use two 10W 4ohm output speakers, it is difficult to use for products with an AMP output exceeding 10W.
Also, due to noise issues, we are only considering ABclass type.

Due to PCB area and height issues, I selected TDA7266D considering lower heat dissipation, but I am concerned about temperature issues.

So for having only 10W : depends on your power supply voltage in first place.

supply is ..?

Maybe TDA7379 , AB , 4 x 11W (at 18V);

Mouser: 511-E-TDA7379
