Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the A-grade designation matches the required ±0.05% accuracy and 10ppm/°C drift specifications. Ensure the HS6 suffix aligns with the –40°C to +125°C operating temperature range requirements for your application environment.

Voltage Reference Selection Notes

Select this part for applications requiring high precision in a compact surface-mount footprint. The buffered output eliminates the need for external amplifiers in many scenarios. Consider the LS8 package variant if superior long-term stability and lower hysteresis are critical, as the plastic SOT-23 package exhibits higher thermal stress sensitivity compared to hermetic options.

Voltage Reference Part Context

This component belongs to the LT6654 family of small precision voltage references designed for portable and industrial equipment. The family offers various output voltages and packages, including the hermetic LS8 for extreme stability. The A-grade designation signifies tighter tolerance limits compared to B-grade parts, ensuring higher initial accuracy across the specified temperature range.
