I was going through the application note by NXP regarding the implementation of the medical alarm based on the IEC 60601-1-8 standard.
It says that the hardware to be used is a DAC followed by a filter.
I was wondering if I'd need a codec or some sort of an audio amplifier before I use the speakers.
Also, if I do implement this algorithm, can I use any speaker?
I'm posting the link to the application note below:
