Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging and lead-free finish. Confirm the 'D' grade designation matches the required 0.1% accuracy and 20ppm/°C drift specifications for your application. Ensure the 8-lead SOIC package footprint aligns with your PCB design constraints.

Voltage Reference Selection Notes

Select this component when low power dissipation is critical compared to shunt references. The series topology allows operation with minimal input-output differential. Verify that the 0.1% initial accuracy and 20ppm/°C temperature coefficient meet system requirements. Consider the 20mA sourcing capability for driving downstream loads directly.
