I tried making amps with this chip, around 8 years ago when it first appeared.

All I managed was to make a number of door-stops!

VERY much more difficult to work with than the TA2020-020, which is quite a simple and superb,easy to use chip

--The Pin-Out of the TA2022 is appalling, (I even complained to Tripath at the time...) making it a necessity to use dual-sided print for the power rails and O/P connections, which by their own requirements need to be short and stout--Impossible to place the chip at the edge of the board and maintain these connection requirements.

--'Orrible chip--I never ever succeeded in making one work even for a second, and as I recall, they were an expensive part, and I forget the number I let the magic smoke out of...!

--Currently, there's a guy selling the original Dev. kits for the 90W per ch. EB-2022-020 on fleagay. Just type Tripath and wade through them, I was thinking of getting one just to see one actually Work!......

I still have my E.B.-TA2020-020 dev. kit, and use it sometimes as a bench-amp for testing etc, Great little thing...

Hi all you digital guys

In mi new incursion into the world of class-D, I have seen this thread which seems to be quite interesting. I almost don't know anything about class-D, so lots of us will be pleased if someone could rescue the old wiki. I cannot find it

Regards,
Regi

Have anyone tried running the TA2020/TA2024 chips in car, directly connected to the 14.2V car supply?
The supply voltage seems to be quite high, but low enough than 16v absolute maximum rating.

Actually, I've had an AMP32 running the front door speakers in my car for about 14 months now. No head unit, no rear sound, just the AMP32 on the front doors and an MP3 player.

I just haven't had the motivation to replace it with anything better. It plays plenty loud enough to satisfy me most of the time.

It will evertually get replaced by 4x hand made TPA3106D1 boards and a 24V SMPS.

The old wiki and the Tripath FAQ is no more. Does anyone still have a copy of the faq?
