ADR5045BKSZ-R2

Overview

The ADR5045BKSZ-R2 is a precision micropower shunt mode voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 5.0 V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 75 ppm/°C. The device operates within a wide current range from 50 µA to 15 mA and functions across an extended temperature range of −40°C to +125°C. Housed in an ultracompact SC-70 (KS) surface-mount package, it requires no external compensation capacitor for stability.

Feature Summary

• Ultracompact SC-70 package design optimized for space-critical applications
• High initial accuracy of ±0.1% with low temperature drift
• Wide operating current range supporting both micropower and higher load conditions
• Stable operation without the need for external compensation capacitors

Applications

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

Procurement Notes

Verify the specific ordering suffix and package type against official documentation to ensure compatibility with design requirements. Confirm RoHS compliance status and automotive qualification if applicable. Check for product discontinuance notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when high precision and compact size are required for shunt reference applications. Ensure the bias resistor calculation accounts for the minimum operating current at the lowest expected supply voltage and maximum load current. Verify that the thermal resistance characteristics suit the intended PCB layout and ambient conditions.

Part Context

This part belongs to the ADR504x family of precision voltage references, which includes variants with different output voltages and accuracy grades. The 'B' designation indicates the higher accuracy grade compared to the 'A' grade. The 'KS' suffix specifies the SC-70 package option, while 'R2' typically denotes reel packaging configuration.

Replacement Considerations

The datasheet notes pin compatibility with LM4040/LM4050 devices. Designers should verify electrical specifications and package dimensions match their existing board layout before substituting these alternatives.
