ADR5044AKSZ-R2

Overview

The ADR5044AKSZ-R2 is a precision micropower shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 4.096 V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 100 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. It is housed in an ultracompact SC-70 (KS) package, designed for space-critical applications without requiring external compensation capacitors.

Feature Summary

• Ultracompact SC-70 package design optimized for space-constrained environments
• High precision performance with low temperature drift characteristics
• Wide operating current range supporting diverse load conditions
• Stable operation without the need for external compensation capacitors

Applications

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

Procurement Notes

Verify the specific suffix 'R2' against official documentation, as standard listings often utilize 'REEL7'. Confirm package type KS-SC-70 matches requirements. Ensure Grade A specifications align with system accuracy needs. Check RoHS compliance status. Validate automotive qualification if applicable to the target environment.

Selection Notes

Select this component when high precision is required in minimal footprint designs. The 4.096 V output suits ADC/DAC references. Consider the 100 ppm/°C drift for thermal stability. Evaluate the 50 µA minimum current for low-power standby modes. Verify compatibility with existing PCB layouts using the SC-70 outline dimensions.

Part Context

Part of the ADR504x family of precision shunt voltage references. Includes variants like ADR5040, ADR5041, ADR5043, and ADR5045 offering different voltages. Shares pinout compatibility with LM4040/LM4050 series. Designed for general-purpose precision referencing in industrial and consumer electronics.

Replacement Considerations

LM4040 and LM4050 series offer pin-compatible alternatives. Verify electrical parameters match specific application requirements before substitution.
