ADR02AKSZ-REEL7

Overview

The ADR02AKSZ-REEL7 is a precision bandgap voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 5 V with an initial accuracy of 0.1% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range of 7 V to 36 V and supports a maximum shunt current of 10 mA. It consumes 1 mA of supply current and exhibits low noise characteristics. The component functions reliably across a wide temperature range from -40°C to +125°C. It is housed in a compact SC-70-5 surface-mount package, suitable for space-constrained designs requiring high stability.

Feature Summary

• Delivers stable 5 V reference output with high initial accuracy
• Features ultra-low temperature drift for thermal stability
• Operates efficiently with minimal supply current consumption
• Designed for robust performance across extended industrial temperatures

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• High-resolution measurement instrumentation systems
• Battery-powered devices requiring stable reference voltages

Procurement Notes

Verify the specific suffix 'KSZ' against the manufacturer's official datasheet to confirm the exact package type and reel specifications. Ensure compatibility with your PCB footprint, as the SC-70-5 package dimensions are critical for surface-mount assembly. Confirm that the 5 V output aligns with your system requirements before procurement. Check for any recent product change notices regarding manufacturing updates or material composition changes.

Selection Notes

Select this component when a fixed 5 V reference with sub-percent accuracy is required. The 3 ppm/°C temperature coefficient makes it suitable for applications sensitive to thermal variations. Consider the 10 mA load capability and 1 mA quiescent current for power budgeting. The SC-70-5 package offers a small form factor compared to larger through-hole alternatives. Evaluate if the fixed output meets your design needs versus adjustable reference options.

Part Context

The ADR02 series comprises precision bandgap voltage references known for low drift and high accuracy. The ADR02AKSZ-REEL7 specifically denotes the 5 V variant in a SC-70-5 package supplied in a reel format. This part belongs to Analog Devices' portfolio of precision analog components designed for demanding measurement and control applications. The 'K' typically indicates the accuracy grade, while 'S' refers to the SC-70 package style.

Replacement Considerations

Consult Analog Devices documentation for direct pin-compatible replacements within the ADR02 family. Verify that alternative parts match the 5 V output, 0.1% accuracy, and SC-70-5 package constraints. Cross-reference temperature coefficients and load current capabilities to ensure functional equivalence in your specific circuit design.
