The goal is to play short audio files of human speech. I'm using a 5V supply voltage. That's the most I have available to me for this design.
Edit: The frequency response of the speaker is described in the data sheet as 100 Hz - 10kHz
Sorry, I'll be more specific. The 500mW is the rated input power of the speaker. I looked at it again on the data sheet and see that it is RMS power.
The signal ACROSS the load is reading on an oscilloscope as a 1.8V peak. I will measure this again when I get the chance but it was definitely...
Hey all, this is my first time on this forum and I really need the help! I'm currently designing an amplifier for a 400mVpk signal (wav file of the human voice coming out of a PCM channel of an STM32 MCU.) I'm using the Taoglas - SPKM.17.8.A - 17mm Mini Speaker.
