Title: Simple Open source LM399 Reference PCB
Post by: RoadRunner on August 26, 2018, 03:30:46 pm
I am doing few experiments with LTC2500 so i needed stable reference voltage, i quickly made this little PCB which some may find interesting. It is open source , Schematic, Gerber and PCB files are available in my github account.

Yes there are few assembled calibrated boards available.
I don't want to make it sale thread. I would post in buy sell section if more people are intrested.

 Attached my data logging and temperature of RoadRunner LM399 board.
Thank you RoadRunner  :-+
