DSP mode(Short frame sync), Fs(min)=8kHz / PWM Modulator , I2C input Audio amp

Hi, Asaka-san,

Can you please provide more information about the system application so we can find the best solution for you?, like output power, processing options, etc. I would like to recommend you to take a look to our Audio Selection Tool as it is a good starting point to find the right device for your application.

Hi, Asaka-san,

Thanks for the information. I am not sure if we have a device compliant with the specs you mention, so, I have asked my colleague that supports PWM modulators to check your question. As he is traveling now, he may be able to get back to you in the next couple of days.
