ADR02BKSZ-REEL7

Overview

The ADR02BKSZ-REEL7 is a precision series voltage reference manufactured by Analog Devices Inc., delivering a nominal output of 5.0 V. It utilizes bandgap technology to provide high accuracy with an initial tolerance of 0.1% and a low temperature coefficient of 3 ppm/°C. The device operates within an input voltage range up to 36 V and supports a maximum shunt current of 10 mA. Designed for surface-mount applications, it is housed in a compact SC-70-5 package and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides stable 5.0 V reference output using precision bandgap architecture
• Ensures high long-term stability with minimal drift over temperature variations
• Features ultracompact SC-70-5 surface-mount packaging for space-constrained designs

Applications

• Precision analog-to-digital converter (ADC) reference inputs
• Data acquisition systems requiring stable voltage sources
• Industrial process control instrumentation
• Medical equipment signal conditioning circuits

Procurement Notes

Verify the specific suffix 'B' indicates the 0.1% initial accuracy grade when sourcing. Confirm the REEL7 designation corresponds to the required tape-and-reel quantity for automated assembly. Ensure the SC-70-5 footprint matches the target PCB layout. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5.0 V output is required with tight initial accuracy and low thermal drift. The SC-70-5 package suits applications where board space is limited compared to larger SOIC or DIP options. Consider the 10 mA load capability against system power consumption requirements. Verify that the 36 V maximum input voltage aligns with the available supply rails in the design.

Part Context

This part belongs to the ADR02 family of ultracompact precision voltage references from Analog Devices. The family includes variants with different output voltages and accuracy grades, such as the ADR02AKSZ and ADR02AUJZ. These devices share common architectural features but differ in specific performance metrics and packaging options to suit diverse electronic design needs.

Replacement Considerations

ADR02AKSZ offers similar functionality with potentially different accuracy grading. ADR02AUJZ provides the same 5.0 V output in a TSOT-23-5 package, requiring footprint adaptation. ADR03BKSZ is a higher-performance alternative with improved noise and drift characteristics.
