ADR02WARZ-REEL7

Overview

The ADR02WARZ-REEL7 is a precision voltage reference from Analog Devices, featuring a fixed output of 5V with an initial accuracy tolerance of ±0.1%. It operates within a supply voltage range of 7V to 36V and delivers a maximum output current of 10mA. The device exhibits a temperature coefficient of 10ppm/°C and low noise characteristics of 10µVp-p in the 0.1Hz to 10Hz bandwidth. Designed for surface mount applications, it utilizes an 8-pin NSOIC package and functions reliably across an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Features low temperature coefficient for stable performance across wide thermal ranges
• Delivers high output current capability without requiring external capacitors
• Incorporates low noise architecture suitable for sensitive signal conditioning

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converters

Procurement Notes

Verify the specific suffix REEL7 indicates reel packaging configuration when sourcing. Confirm the NSOIC-8 package variant matches your PCB footprint requirements. Ensure input voltage remains within the 7V to 36V operational limits during system design validation. Cross-reference the temperature coefficient specifications against your environmental operating conditions.

Selection Notes

Select this component when a fixed 5V reference with ±0.1% accuracy is required in an 8-pin SOIC package. Consider the 10ppm/°C temperature drift for applications demanding stability over wide temperature variations. Evaluate the 10mA output drive capability against load requirements to ensure sufficient margin for downstream circuitry operation.

Part Context

This part belongs to the ADR02 series of ultra-compact precision voltage references manufactured by Analog Devices. The series includes variants with different packages such as SC70 and TSOT, offering flexibility for space-constrained designs. The ADR02WARZ-REEL7 specifically provides the robust 8-pin SOIC form factor while maintaining the series' core precision and low-noise characteristics.

Replacement Considerations

Direct substitutes include other ADR02 series variants like ADR02ARZ or ADR02BUJ depending on package preference. Verify pinout compatibility and electrical parameter alignment before substitution. Alternative precision references from other manufacturers may require circuit redesign due to differing pin configurations or performance metrics.
