--00151747553ee242a504c19664f1 Content-Type: text/plain; charset=ISO-8859-1 I am using a microchip microcontroller to read in a 8ks 16 bit .wav file and output it through the dac. I have a small 109 dB speaker 32 ohm impedance, nominal input power of 12mW and max input power of 20mW for 1 minute. I haven't done anything like this in years. I don't want volume control just the loudest possible. How do I limit the power going to the speaker? Can anyone point me in a direction? --00151747553ee242a504c19664f1 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable <div>I am using a microchip microcontroller to read in a 8ks 16 bit=A0.wav = file and output it through the dac.=A0 I have a small 109 dB speaker 32 ohm= impedance, nominal input power of 12mW and max input power of 20mW for 1 m= inute.</div> <div>=A0</div><div>I haven't done anything like this in years.=A0 I=A0d= on't want volume control just the loudest possible.=A0 How do I limit t= he power going to the speaker?=A0 Can anyone point me in a direction?</div> --00151747553ee242a504c19664f1--
