Description:

The voltage standard uses the LM399 for Linear Technology as the reference element, with two sets of voltage outputs 6.95V/10V. 6.95V is the direct output of LM399. 10V is 6.95V outputted to 10V after being boosted by a precision op amp.

The LM399 reference IC is used as a reference IC in many 6 u00bd digit multimeters and is a constant temperature reference. Compared with 4 u00bd digit references such as AD584 and BQ588, its temperature coefficient is much smaller, and basically does not exceed 0.5PPM/°C. It can be used as a 5 u00bd digit or 6 u00bd digit voltage reference.
