REF35102 - High-Precision Voltage Reference

Download the REF35102 datasheet PDF. This datasheet also covers the REF35 variant, as both devices belong to the same high-precision voltage reference family and are provided as variant models within a single manufacturer datasheet.

Description

The REF35 is a family of nanopower, low-drift, highprecision series reference devices.

Features

  • Ultra-low quiescent current:.
  • 650nA (typical).
  • Initial accuracy: ±0.05% (maximum).
  • Temperature coefficient (maximum):.
  • 12ppm/°C (.
  • 40°C to 105°C, SOT23 package).
  • 10ppm/°C (.
  • 40°C to 85°C, WCSP package).
  • Output 1/f noise (0.1Hz to 10Hz): 3.3ppmP-P.
  • NR pin to reduce noise.
  • EN pin to reduce shutdown current consumption.
  • Long-term stability: 40ppm at 1k hour.
  • Thermal hysteresis: 70ppm.
