pwm pure sine wave generator

[mord]

I want to know the various ICs that can be used to generate pwm sine wave. I was able to get one on google but not with much design support. HT1112 IC. Please help me out. I dont really want to deal with programming microcontrollers as I do know they can be used.

Hi
Probably these Chinese ICs are the only ASIC that I know which are for sine wave generation and inverter application.
Does anybody know any other IC?
Thanks

if you are looking for a sine wave generator DDS chips are very accurate, e.g.

Thanks horace1, but I find it hard to understand the information I got from your links. What I need are S.H.E ICs to generate sine wave for inverter. Single Harmonic Elimination.

in a project a few years ago we used two DDS modulators (Analogue Devices AD7008JP50 now obsolete) to generate two very pure sine waves varyiing in frequency from 1Hz up to 10MHz with a specified phase differemce
if you do a web search on DDS generator or similar it will give you plenty of links, e.g.
