Hi Kuramochi,

Thank you for your patience.

What is the customer's application where they are concerned about audible noise?

The internal oscillator is designed to have a frequency high enough to not interfere with audible frequency.

Kate

Kate-san,

Thank you for your reply.

Customer's application is musical instruments.

Is internal oscillator over 1MHz?

Hi Kuramochi-san,

Thank you for that information.

I am checking with the designers, but the frequency of the internal oscillator is outside of the audio band, so it should not be observable and will not interfere with any audible sound.

Best regards,

Kate

I have confirmed that both internal oscillators for TIC12400 operate at frequencies outside of the audio band. Please let me know if you have any additional questions!
