ADR130AUJZ-R2

Overview

The ADR130AUJZ-R2 is a precision series sub-band gap voltage reference manufactured by Analog Devices Inc. It operates within an input voltage range of 2.0 V to 18 V and provides fixed output voltages of 0.5 V or 1.0 V, selected via the SET pin configuration. The device features low quiescent current consumption of 80 μA typical and supports load currents up to +4 mA source and -2 mA sink. It offers initial accuracy grades of ±0.70% (A grade) or ±0.35% (B grade), with maximum temperature coefficients of 50 ppm/°C or 25 ppm/°C respectively. The component functions reliably across a specified temperature range from −40°C to +125°C.

Feature Summary

• Housed in a tiny, lead-free TSOT-23 package designed for space-constrained applications.
• Capable of delivering high precision performance while maintaining micropower operation suitable for battery-powered systems.

Applications

• Battery-powered instrumentation
• Portable medical equipment
• Communication infrastructure equipment

Procurement Notes

Verify the specific grade (A or B) required for your application, as the base part number does not explicitly denote the accuracy tier in the provided text. Confirm that the REEL7 suffix aligns with your manufacturing packaging requirements. Ensure the SET pin is correctly tied to either VOUT or GND to achieve the desired 0.5 V or 1.0 V output level before finalizing procurement specifications.

Selection Notes

Select the A grade if ±0.70% initial accuracy and 50 ppm/°C temperature coefficient are sufficient. Choose the B grade for tighter tolerances requiring ±0.35% accuracy and 25 ppm/°C drift. Consider the low 80 μA quiescent current when designing for extended battery life. Ensure the input voltage remains within the 2.0 V to 18 V range to maintain stable regulation and prevent excessive power dissipation.

Part Context

The ADR130AUJZ-R2 belongs to the ADR130 family, which represents the first generation of tiny, micropower, low voltage, high precision voltage references in its class. This family utilizes a sub-band gap architecture to achieve high performance in a compact form factor. The AUJZ designation indicates the specific TSOT-6 package variant compliant with RoHS standards.
