ADR444ARZ General Description

The ADR440/ADR441/ADR443/ADR444/ADR445 series is a family of XFET^® voltage references featuring ultralow noise, high accuracy, and low temperature drift performance. Using Analog Devices, Inc., patented temperature drift curvature correction and XFET (eXtra implanted junction FET) technology, voltage change vs. temperature nonlinearity in the ADR440/ADR441/ADR443/ADR444/ADR445 is greatly minimized.

Key Features

Ultralow noise (0.1 Hz to 10 Hz)

ADR440: 1 μV p-p
ADR441: 1.2 μV p-p
ADR443: 1.4 μV p-p
ADR444: 1.8 μV p-p
ADR445: 2.25 μV p-p

Superb temperature coefficient

A Grade: 10 ppm/°C
B Grade: 3 ppm/°C
