Folks Per our discussions today on Teamspeak, here are the
products under consideration. I have forgotten the parts mentioned by N4HY as
being good candidates. Phil K3IB mentioned he might be willing to put the
associated parts around these chips to give us high quality digitization, and
features we are requesting. There is no rush on this, let’s make a good
choice of parts. Resources assembled by Don - AE5K Wolfson chips: WM8785 adc general info

find by Phil Covington would be of use! Just A/D and a FPGA! (course a good
front end and FX2 in the back) I almost fell out of my chair when Phil mentioned this in a
PM several weeks ago! Hope I'm not stepping on any toes here Phil! http://www.analog.com/UploadedFiles/Data_Sheets/374764955AD9446_0.pdf We have had quite a bit of Discussion regarding the above
candidates. Several features are desirable as Bill - KD5TFD mentions High Quality Readily Available Easy to handle for experimenters Comments? Eric |
