ranganatennakoon:
can we make DAC sine wave inverter?
i think, if we can use DAC for making sine wave inverter it is batter than spwm :-BROKE
coromonadalix:
For a pure sine wave ??? low thd, low jitter, precision ? up to witch frequency ?
You can make sine wave by other means too ?
A cheap way of doing it :

You can make it with some mcu with added filtering
The list goes on and on
Prehistoricman:
SPWM is essentially a class D amplifier. High efficiency. Most DACs (thinking of audio output ICs) would use less efficient class A output drivers.
Which is better completely depends on the application.
David Hess:
You can but efficiency is limited to about 66% because of the linear output stage. A class-D amplifier can be 95% efficient or better.
