Voltage Reference Procurement Notes

Verify the specific suffix 'CMFX' against official Texas Instruments documentation to confirm the exact tolerance grade and reel packaging configuration. Ensure compatibility with standard SOT-23-5 footprints during PCB layout. Cross-reference the datasheet for thermal dissipation requirements under maximum load conditions to prevent overheating in enclosed environments.

Voltage Reference Selection Notes

Select this component when a 2.048 V reference with ±0.2% initial accuracy is required in a small form factor. Consider the 30 ppm/°C temperature coefficient for environmental stability needs. Evaluate the 60 µA quiescent current against system power budgets. Confirm that the SOT-23-5 package dimensions fit the mechanical constraints of the target design.
