jnorv Posted April 14, 2003 Share Posted April 14, 2003 I think I have found a source for tripath products. Now I have to decide which one to get. I am leaning towards the 2020 (2x10 watts) because it runs at 13.5 volts and I can run it off of a standard 12v car battery, rather than the 2024 which runs at 12 volts. Any advice?

jnorv Posted April 3, 2004 Author Share Posted April 3, 2004 Premier Technical Sales in Mountain View, Ca. Being in San Jose, it was easy to just drive up and pick up the amps. They wanted a purchase order, so I had to find a website to gin one up. http://www.ptsi.com/offices.cfm Jim N Quote Link to comment Share on other sites More sharing options...
leok Posted April 4, 2004 Share Posted April 4, 2004 Jim, One big advantage of the TA2020 is that it is a thru-hole part. As far as voltage: Both parts have an absolute max voltage rating of 16V. Operating max for the TA2024 is 13.2V. For the 2020 it's 14.6V. These voltages are all accurate in that the chips will operate at the max operating Voltages, withstand an occasional 16V surge, but will probably self destruct if operated for any length of time at something like 15V. The reason I use the smaller smt parts is 1) I'm actually interested in the lowest power possible and 2) I am using smt pc board technology to keep the circuit as small as possible for noise reduction. If I were building just a few of these I'd go with the TA2020. Leo Quote Link to comment Share on other sites More sharing options...
jnorv Posted April 4, 2004 Author Share Posted April 4, 2004 As an ME, i just bought the 2020 eval boards and am runing them unmodified. They sound just fine to my untrained ear. Jim Quote Link to comment Share on other sites More sharing options...
leok Posted April 4, 2004 Share Posted April 4, 2004 Jim, If you ever decide to, there's an electrolytic cap supplying power to each set of output "switches." You can add a parallel capacitance of 10x whatever there is there (for the two caps). It'll tighten up the bass. The demo boards are very well done, and quite a bargain.
