ADR5043AKSZ-R2

Overview

The ADR5043AKSZ-R2 is a precision micropower shunt mode voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 3.0 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-3) surface-mount package.

Feature Summary

• Designed for space-critical applications using an ultracompact SC-70 package
• Eliminates the need for external compensation capacitors while remaining stable with any capacitive load
• Features low temperature drift and fast settling time for high precision data acquisition

Applications

• Portable, battery-powered equipment
• Automotives
• Data acquisition systems
• Instrumentation and process control

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and check for specific automotive qualification requirements if applicable to your design. Review the latest datasheet revision for any specification updates before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 3.0 V reference is required in a minimal footprint. Ensure the bias resistor calculation accommodates the minimum operating current of 50 µA at the lowest supply voltage and the maximum current limit of 15 mA at the highest supply voltage. Consider stacking multiple units if higher voltages are needed.

Part Context

This part belongs to the ADR504x family of precision micropower shunt voltage references, which includes variants with outputs of 2.048 V, 2.5 V, 4.096 V, and 5.0 V. The family shares similar architectural features, including pin compatibility with LM4040/LM4050 devices and availability in both SC-70 and SOT-23 packages.

Replacement Considerations

LM4040 and LM4050 are pin-compatible alternatives. Verify that their electrical characteristics, particularly temperature coefficients and initial accuracy grades, meet the specific design requirements before substitution.
