Re: STM32F4 + amlifier STA508
This amplifier contains only transistors that amplify PWM pulses is filtered and then see the picture m but instead "C block" is STM32. Unfortunately I can not use PWM because clock frequency of 168MHz and audio sampling 48kHz ( 168Mhz / 48kHz = 3500 quantization levels cca 10 bit instead 24 bit (16 ...

STM32F4 + amlifier STA508
Hello,
I am doing a program where processing audio signal with sampling frequency of 48 kHz and 24 bit. To amplify sound using digital amplifier STA508. Amplifier has only transistors and input signal to be "PWM". Unfortunately, I don't know how to get such a "PWM" from the processor. PWM doesn't ...
