Re: [Xylo-SDR] Latest S3 ADC schematic



Leon

Thanks, very clean layout. What CAD program are you using? We had a
discussion on Teamspeak Xylo forum yesterday and tried to get a consensus.
If we were on the same page with CAD we could probably do an SVN or similar
as we design stuff.

Phil - VK6APH has suggested that we go a board production probably with the
TI chips to work with the Xylo/Saxo. We have not decided on the A/D but the
TI chips really look like the way to go since they are readily available
here in the States from Digi-Key and the AD has almost the same specs as the
Cirrus offering. It is about 1/2 the cost.

Incidentally I have suggested that we have a Xylo group Teamspeak discussion
on Saturdays at 1700 so that those interested in this group in EU can
participate. Ahti? Leon? Others in EU? WATSA?

Eric

I've simplified my schematic considerably by utilising the MC33204/2 op 
amps:

They are single-supply op amps, with rail to rail operation on both inputs 
and outputs.

A happy New Year to everyone,

Leon
