I'm using a STM32F469i- discovery board for developing a prototype & would like to use the Audio DAC feature in it and it is given in the datasheet that one set of pins (15 & 16 in CN12). I checked this discovery board's and also the controller's dat...

since the PWM driver of cirrus logic is powered by 3V3, I should then consider only 2.5V rms as 3V3/1.414 is roughly 2.3V rms..so while choosing a 4 ohm speaker I have to choose a speaker that is rated say 0.5W then the speaker will be safely drive...

I mean that I understood so only I have asked since the PWM of cirrus logic is powered by 3V3, I should then consider only 2.5V as 3V3/1.414 is roughly 2.3V rms..so while choosing a 4 ohm speaker I have to choose a speaker that is rated say 0.5W the...

Sorry I have not framed the sentence properly, but yeah I didnt mention as in the IC there, I was meaning the STM32 development board had an audio codec, so yeah that wasnt my doubt, my doubt was that since the audio codec is being controlled by the ...

Oh I see, Duly Noted. One more small clarification, so that I can ask the people at Cirrus logic clearly, the output we are talking about, i.e 3.7V this value is given(outputted) by the Cirrus logic codec, right?so what voltage value is provided by t...

Oh so, since this STM32 disco board is already having a Audio codec, I can directly plug in the speakers to the mentioned pins(CN12- pins 15 &16), and from the Datasheet you have shared earlier, I can see that I can connect a 4 ohm speaker having a r...
