View Full Version : Zetex PWM
Found some intreresting stuff, some high quality ic brand making an intreresting class d driver. converts direcly the digital signal to pwm. dunno if its interesting, but could replace tripath when sold out :)
Actually, before tripath "died" they also experimented, or was going to release some direct digital 24-Bit to PWM 1-Bit.
This would rock! But i think its hart to get hands on those chips...
Hey, I just now ran in to this thread! :)
Yes I've seen them, they're pretty promising although I'm afraid they won't quite replace the magic of Tripath... Although I have no first hand experience with these products at all...
------X-max. can be several meters on any driver, too bad it can be done only once...------
My thoughts exactly - Tripath can be imitated, but never replaced.
There can be only ONE.

I have never tried other brands ClassD.
The first time I came across this site (41Hz), I was amazed by the fact that the amp modules are relative cheaper than other brands.
After I built one myself, I am also very impressed by the sound quality of it.
Can anyone give more comments ?
I am interested in how Tripath would compared with some other brands, like Gainclone based, UcD, NewClassD, etc...
Ive made a few gainclones and they sound sweet.
The problem with them is they are not nearly as efficient as the the tripath chips and give off large amounts of heat. The minimum power requirements for most is a 160VA transformer.
They also require a sort of dual rail power ie +V GND -V and the star earth/ground has to be well sorted or a ground loop gives massive hum.
Ive used the tripath amps in my small amp or powered speaker projects and they do the job very well.
