REF35 - High-Precision Voltage Reference

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 (.
