What is it?

LM399 Reference board, Its a little board made which take 15V input and Give you really precision 10.000000V output. So that you can calibrate and check your ADC, Multimeter or any other device which can make use of precision 10.000000V

Why did you make it?

While working in my lab I often need to check my multimeter, ADC circuits and other circuits that needed precise voltage. While working a 32-bit ADC board i decided to quickly make this reference board to test performance of 32-bit ADC.

What makes it special?

Completey open source you can download all PCB file and other source and make your own. its made with Really Precision and stable LM399AH along with LT1001ACN8, Along with Top quality 10PPM resistors high quality 20 turn pot has been used for calibration, Top quality Wago connectors for input and output, There is with MOSFET based reverse polarity protection. Hand made in Germany Calibrated with Keithly DMM7510 7.5 Digit multimeter. With 7.5 Digits meter at 10V resolution is 1uV.

There are Two versions available of this board one with LM399AH with LT1001ACN8 and another with LM399H with LT1001CS8 Here differences.

LM399H 0.3ppm Typical max 2 ppm/C with 14uV V/C Max @ 10C delta 7.000140V LM399AH 0.3ppm Typical max 2 ppm/C with 7uV V/C Max @ 10C delta 7.000070V

Board with LM399AH cost more as BOM cost has huge difference.

Board size 48mm x 100mm x 19mm
