• 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
• Automotive systems
• Data acquisition systems
• Instrumentation and process control
• Energy management

Procurement Notes

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

Selection Notes

Select this component when a 5.0 V reference is required in a minimal footprint design. 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 to maintain stability.

Part Context

This part belongs to the ADR504x family of precision shunt voltage references, which includes variants with different output voltages (2.048 V, 2.5 V, 3.0 V, 4.096 V) and accuracy grades. The ARTZ suffix indicates the SOT-23-3 package option, distinguishing it from the KS-SC70 package variant.

Replacement Considerations

The datasheet notes pin compatibility with LM4040/LM4050 devices. Designers should verify electrical parameters such as temperature coefficient and operating current limits against these alternatives to ensure circuit stability.
