Voltage Reference Procurement Notes

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

Voltage Reference Selection Notes

Select this component for designs requiring high precision in compact surface-mount layouts. The buffered output eliminates the need for external op-amps in many low-current applications. Consider the 100mV dropout voltage for battery-powered or low-headroom scenarios. Verify that the 1µF minimum output capacitor requirement fits within the board space constraints.

Voltage Reference Part Context

This part belongs to the LT6654 family of small precision voltage references designed for high accuracy and low noise. The family includes various output voltages and packages, such as the LS8 hermetic option. The A-grade designation signifies tighter tolerance specifications compared to B-grade variants, making it suitable for critical measurement applications.
