ADR530ARTZ-REEL7

Overview

The ADR530ARTZ-REEL7 is a high precision shunt voltage reference from Analog Devices, housed in an ultracompact 3-Lead SOT-23-3 package. It provides a nominal output voltage of 3.0 V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 70 ppm/°C. The device operates within an industrial temperature range of −40°C to +85°C and requires a minimum operating current of 50 μA up to a maximum of 15 mA. Designed for space-critical applications, it eliminates the need for external compensation capacitors while maintaining stability with any capacitive load.

Feature Summary

• Ultracompact 3-Lead SOT-23-3 package designed for space-critical applications
• Pin compatible with LM4040/LM4050 devices
• No external capacitor required for operation
• Trim terminal available for adjusting output voltage over a ±0.5% range

Applications

• Portable, battery-powered equipment
• Automotive systems
• Data acquisition systems
• Instrumentation and process control
• Energy measurement

Procurement Notes

Verify the specific grade suffix (ART) against the ordering guide to confirm the 70 ppm/°C temperature coefficient and ±0.4% initial accuracy specifications. Ensure the REEL7 packaging option matches the production volume requirements. Confirm RoHS compliance status indicated by the Z suffix. Cross-reference the pinout configuration to ensure compatibility with existing PCB layouts designed for standard SOT-23-3 footprints.

Selection Notes

Select this component when a 3.0 V reference is required in a minimal footprint without external compensation components. The Grade A specification offers a wider operating current range suitable for varying load conditions. Consider the trim terminal if system-level calibration is necessary to offset initial accuracy errors. Verify that the 70 ppm/°C drift meets the thermal stability requirements of the target application environment.

Part Context

This part belongs to the ADR520/ADR525/ADR530/ADR540/ADR550 series of high precision shunt voltage references. These devices utilize a band gap concept to produce stable references suitable for high accuracy data acquisition components. The series is characterized by low temperature drift and ultralow output noise, making them ideal for handheld and battery-powered applications where power consumption and size are critical constraints.
