Product Summary

The ADR431AR is a XFET voltage reference featuring low noise, high accuracy, and low temperature drift performance. Using ADIs patented temperature drift curvature correction and XFET (eXtra implanted junction FET) technology, the ADR431AR voltage change versus temperature nonlinearity is minimized. Applications are (1)Precision data acquisition systems; (2)High resolution data converters; (3)Medical instruments; (4)Industrial process control systems; (5)Optical control circuits; (6)Precision instruments.

Parametrics

ADR431AR absolute maximum ratings: (1)Supply Voltage: 20 V; (2)Storage Temperature Range (R, RM Packages): −65°C to +125°C; (3)Operating Temperature Range: −40°C to +125°C; (4)Junction Temperature Range: −65°C to +150°C; (5)Lead Temperature Range (Soldering, 60 s): 300°C.

Features

ADR431AR features: (1)Low noise (0.1 Hz to 10 Hz): 3.5 μV p-p @ 2.5 V output; (2)No external capacitor required; (3)Low temperature coefficient A Grade: 10 ppm/°C max, B Grade: 3 ppm/°C max; (4)Load regulation: 15 ppm/mA; (5)Line regulation: 20 ppm/V; (6)Wide operating range.
