[sdiy] A/D converter with good accuracy for a reasonable price?

[Karl Ekdahl]

Hi list

I'm trying to find a decent A/D for converting pitch-CV into digital, given this it needs to be fairly accurate and probably at least 14 bits. Seems to me it's hard to find anything that's not like $25 a piece. It only needs to have one converter (i'll use a multiplexer in front of it) and i guess a sample rate would be whatever would be apropriate for a seemingly seamless variation in pitch - a few 100 samples per second? 

I was looking at the CS5510, but it strikes me as it might be too slow and also the +-7 LSB^16 bipolar offset error scares me even tho i'm not 100% sure what it means :)

Any input / suggestions highly apprecited.
