Other Parts Discussed in Thread: TLE2425

Is there any reason the TLE2425 could not be used over the REF5025 for reference of an A/D converter?

Thanks,

I'm not familiar with the TLE2425, so I'm not sure what other issues might come up.

However, I'd say that the biggest problem would be the noise. In the TLE2425, the noise is listed as 100uV of rms noise, where the REF5025 is about 7.5uV p-p. While the bandwidths different for the given specifications, it's pretty clear to me that the TLE2425 is far noisier. Since you're generating the digital code from this reference, you would have much more noise in the reading.
