ADR4530ARZ-R7

Overview

The ADR4530ARZ-R7 is a high-precision, low-power voltage reference providing a fixed 3.000 V output. It features an initial output voltage error of ±0.02% for B grade and ±0.04% for A grade. The device operates over an extended temperature range of −40°C to +125°C with a maximum temperature coefficient of 2 ppm/°C (B grade) or 4 ppm/°C (A grade). Quiescent current is limited to 950 μA maximum, and it supports ±10 mA sourcing and sinking output currents.

Feature Summary

• Utilizes innovative core topology for industry-leading temperature stability and noise performance
• Features low thermally induced output voltage hysteresis and low long-term drift
• Capable of sourcing and sinking load currents up to 10 mA

Applications

• Precision data acquisition systems
• High resolution data converters
• Industrial instrumentation
• Medical devices

Procurement Notes

Verify the specific grade (A or B) required for your application, as temperature coefficients and initial errors differ between grades. Confirm that the R7 suffix indicates tape and reel packaging suitable for automated assembly. Ensure input voltage remains within the specified 3.1 V to 15 V range during operation.

Selection Notes

Select this component when ultralow noise and high accuracy are critical for system precision. Consider the A grade if wider temperature coefficient limits are acceptable, or the B grade for tighter thermal stability specifications. Evaluate the 8-lead SOIC package constraints against available PCB space and thermal dissipation requirements.

Part Context

This part belongs to the ADR45xx series of ultralow noise, high accuracy voltage references from Analog Devices. The family includes various fixed output voltages such as 2.048 V, 2.5 V, 3.3 V, 4.096 V, and 5.0 V, all sharing similar architectural benefits regarding power consumption and noise characteristics.
