Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the AIS6 designation corresponds to the required –40°C to 85°C operating range. Ensure compatibility with standard surface mount assembly processes for the TSOT-23 package. Cross-reference the manufacturer part number against official distributor catalogs to confirm current availability status.

Voltage Reference Selection Notes

Select this component for designs requiring precise voltage references in space-constrained environments. The TSOT-23 package offers a low profile suitable for portable equipment. Consider the 10ppm/°C drift specification for applications demanding stability across the industrial temperature range. Evaluate the 600µA supply current against power budget constraints for battery-operated devices.

Voltage Reference Part Context

This part belongs to the LT6654 family of small precision voltage references designed for wide supply ranges up to 36V. The family includes various output voltages and grades, such as the H-grade for extended temperatures and MP-grade for automotive use. The LS8 hermetic package option is available for applications requiring superior long-term stability and lower hysteresis compared to the plastic TSOT-23 variant.

Voltage Reference FAQ

Can the LT6654AIS6-2.048 operate as a negative voltage reference?

Yes, by connecting the output to a negative rail and biasing the internal circuitry with a positive voltage at the VIN pin through a current-limiting resistor.

What is the minimum required output capacitance for stable operation?

An output capacitor of 1µF or greater is required to ensure stability, with 1µF being the optimum value for most applications.
