DIY voltage and current reference

Petteri Aimonen designed and built his own voltage and current reference: When developing a data acquisition system, I ran into a need of having fairly accurate current reference to compare against, 0.1% accuracy or better. This is not a particularly high standard, but unable to find a...

Lowest-drift bandgap voltage reference reaches 1.5ppm/°C, offers low dropout

by Graham Prophet @ edn-europe.com: LT6657 is a family of ultra-stable bandgap voltage references that exhibits less than 1.5ppm/°C of temperature drift. Reinforcing this performance, the device has only 0.5ppm p-p of low frequency noise, less than 30 ppm of long term drift and 35...
