Very interesting article, thanks for posting.

MAX6126 is clearly a bandgap reference

(From maxim-ic.com)
SUNNYVALE, CA-November 13, 2002-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX6126, the industry's lowest noise, ultra-precision bandgap voltage reference.

INDUSTRY'S LOWEST NOISE, ULTRA-PRECISION, VOLTAGE REFERENCE IDEAL FOR HIGH-RESOLUTION DACs - New Product Release

Nationals own best reference LM329 is a buried Zener reference, which according to the article above has much lower basic noise. A reading of datasheets show a difference of something like 3 times more noise in MAX6126 compared to LM329. The article says 6 - 30 times difference.

Did anyone make a direct comparison of these two voltage references?
