Procurement Notes

Verify the specific suffix (e.g., T for reel) against your manufacturing requirements. Confirm RoHS compliance status through official documentation. Check current availability as distribution may be limited or restricted. Ensure the operating temperature range meets your environmental specifications. Validate pinout compatibility during integration planning.

Selection Notes

Select this part when a fixed 1.8 V reference is required with high precision. Consider the 6 PPM/C temperature coefficient for thermal stability needs. Evaluate the 5 mA load capability against circuit demands. Compare supply current consumption with alternative references for power optimization. Verify package footprint alignment with existing PCB layouts.

Part Context

This component belongs to the MAX6068A series of precision voltage references. It shares architectural similarities with other Maxim micropower references but offers specific output voltage and accuracy characteristics. The series targets applications demanding low noise and high stability in small packages.

Replacement Considerations

Check for direct substitutes within the MAX6068 family offering different voltages. Verify pin-compatible alternatives from Analog Devices if sourcing is constrained. Ensure functional equivalence regarding dropout voltage and load regulation capabilities.
