Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the E grade designation corresponds to the required –40°C to 85°C industrial temperature range and ±0.125% accuracy specifications. Ensure the S8 package type matches the PCB footprint requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status and lead-free finish compliance.

Voltage Reference Selection Notes

Select this component for applications requiring a fixed 5V reference with industrial temperature stability. The 20mA sourcing capability allows direct drive of moderate loads. Consider the 20ppm/°C temperature coefficient for thermal environments exceeding commercial limits. Verify that the 0.9V dropout voltage fits within the available input voltage headroom. Evaluate the 225µA supply current against system power budgets compared to shunt references.
