REF70 - high precision series voltage references

Datasheet Summary

Description

The REF70 is a family of high precision series voltage references that offers the industry’s lowest noise (0.23 ppmp-p), very low temperature drift coefficient (2 ppm/°C), and high accuracy (±0.025%).

Features

  • Low noise enables precision measurements:.
  • 1/f Noise (0.1 Hz to 10 Hz): 0.23 ppmp-p.
  • 10 Hz to 1 kHz: 0.35 ppmrms.
  • Low temperature drift coefficient:.
  • 2 ppm/°C maximum (-40°C to 125°C).
  • High accuracy: ±0.025% maximum.
  • Humidity resistant hermetic ceramic package (LCCC).
  • Excellent long-term stability (1k hr): 35 ppm.
  • Low dropout: 400 mV.
  • Designed for a wide range of.
