Distortion of TDA7297 at 40kHz~80kHz

[Mark_You]

Hello, I would like to know the distortion of TDA7297 at 40kHz~80kHz. If it's distortion may over 1%, please give some alternatives. Thanks.

Hello @Mark_You 

According to the datasheet, the distortion is always <1%. 

Best regards.

I think these THD values only apply to frequencies <= 20 kHz, as shown in the diagram.
Which is quite common for audio devices.

So I guess you really have to test that.
I know these problems for years now, using audio ICs for measurement tasks > 20 kHz.
There's nothing sure unless you test it.
