Procurement Notes

Verify the specific ordering suffix KSZ indicates the SC70 package configuration and RoHS compliance status before procurement. Confirm that the REEL7 designation matches the required tape and reel quantity specifications for automated assembly processes. Ensure the component grade B meets the strict accuracy requirements for the intended circuit design.

Selection Notes

Select this component when high precision is required in minimal footprint designs. The wide operating current range allows flexibility in bias resistor selection for varying supply conditions. Verify that the thermal resistance characteristics of the SC70 package are sufficient for the expected power dissipation in the target application environment.

Part Context

This part belongs to the ADR504x family of micropower shunt voltage references, which includes variants with different output voltages such as 2.048 V, 2.5 V, 4.096 V, and 5.0 V. The family shares common architectural features including band gap technology and fast settling times, offering designers a standardized interface for various reference voltage needs in compact electronic systems.

Replacement Considerations
