Default Digital amp (Tripath)

Check out the article on my website below about building an amp around the Tripath EB-TA01014--this may help you to decide.

Note--the EB-TA01014 is about to be discontinued soon, and will be replaced with another eval board (sorry-I don't have the model number at my fingertips, but it's on the Tripath website--www.tripath.com).

Brian,

"Best" is not really an answer that can be provided based on the limited information in your question. If you search the forum you will find several posts on this subject which may be of interest to you. Here is some info:

Methods:

1. Analog input (not recommended (by me) for digital designs since digital switching amps essentially are analog to digtal converters followed by a digital to analog power stage. Thus you get a DAC followed by an ADC in the chain unecessarily if you are coming from a digital source.

2. Digital input. This is the future. Most of the vendors seem more or less paralyzed when it comes to actually shipping anything in this category. You can get the benefit of analog input (and problems associated with that approach) if you add an ADC on the input.

3. "Other" which is more related to modulating power stage. I am not particularly fond of this category but it is interesting nevertheless.


Vendors:

Digital (Yeah!):
Texas Instruments (I would say TI has thought leadership)
Cirrus Logic (low power, very high switching speed)
Apogee
(B&O, but OEM only?)
Some of the Japanese vendors are starting to use switching outputs on their devices but that is typically for internal use only.

Analog input:
Tripath (possibly thought leadership in modulation scheme. There is a rumour that they are getting ready to deliver on their 4 year old promise to ship a digital solution which will be interesting. These guys ship powerful boards)
KM Madsen (search forum or go to www.cadaudio.dk.)
Linfinity
Harris (now on-semi?)
LC Audio (www.lcaudio.com)
Some of the Japanese vendors are starting to use switching outputs on their devices but that is typically for internal use only.

I have probably forgotten about a bunch of manufacturers but the most important ones are shown above.

Petter
