ADR5043AKSZ-REEL

Overview

The ADR5043AKSZ-REEL7 is a precision micropower shunt voltage reference from Analog Devices, housed in an ultracompact SC-70 (KS-3) package. It provides a nominal output voltage of 3.0 V with Grade B initial accuracy of ±0.1% and a maximum temperature coefficient of 75 ppm/°C. The device operates within a wide current range of 50 µA to 15 mA and functions across an extended temperature range of −40°C to +125°C. Designed for space-critical applications, it eliminates the need for external compensation capacitors while maintaining stability with any capacitive load.

Feature Summary

• Ultracompact SC-70 packaging designed for space-constrained environments
• High initial accuracy of ±0.1% with low temperature drift characteristics
• Wide operating current range supporting diverse biasing requirements
• Stable operation without requiring external compensation capacitors

Applications

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

Procurement Notes

Verify the specific ordering suffix REEL7 indicates reel packaging configuration when sourcing. Confirm that the AKSZ designation corresponds to the SC-70 package variant required for your layout. Ensure compatibility with RoHS compliance standards if applicable to your manufacturing process. Cross-reference the marking code R2S for identification during assembly inspection.

Selection Notes

Select this component when high precision is required in minimal footprint designs. The 3.0 V output suits applications needing stable references without level shifting. Consider the 75 ppm/°C drift limit against environmental thermal variations. Evaluate the 50 µA minimum current constraint against system standby power budgets.

Part Context

This part belongs to the ADR504x family of precision micropower shunt voltage references. The family includes variants with different output voltages such as 2.048 V, 2.5 V, 4.096 V, and 5.0 V. The ADR5043 specifically targets the 3.0 V requirement. Variants exist in both SC-70 and SOT-23 packages, with automotive-qualified versions available for specialized reliability needs.

Replacement Considerations

The datasheet notes pin compatibility with LM4040 and LM4050 series devices. Designers should verify electrical parameter alignment before substitution. No other direct substitute part numbers are explicitly confirmed in the provided documentation.
