Procurement Notes

Verify that the specific suffix ARTZ corresponds to the SOT-23-3 package configuration required for your design. Confirm that the Grade A accuracy specification aligns with your circuit tolerance requirements. Ensure the ordering quantity matches the reel packaging specifications provided by the distributor. Check for any automotive qualification requirements if the application demands controlled manufacturing standards.

Selection Notes

Select this component when a stable 4.096 V reference is needed in a small footprint. The Grade A accuracy and 100 ppm/°C temperature coefficient suit general precision applications. Consider the minimum operating current of 50 µA for low-power designs. Verify that the load conditions allow the shunt current to remain within the specified 50 µA to 15 mA range for optimal performance.

Part Context

This part belongs to the ADR504x family of precision micropower shunt voltage references, which includes variants with different output voltages such as 2.048 V, 2.5 V, 3.0 V, and 5.0 V. The family shares common architectural features including band gap technology and ultracompact packaging options like SC-70 and SOT-23. These devices are designed to eliminate the need for external capacitors while maintaining stability with any capacitive load.
