LT6654BHLS8-4.096#PBF

Voltage Reference Overview

The LT6654BHLS8-4.096#PBF is a precision voltage reference featuring a fixed 4.096V output with ±0.1% initial accuracy and a maximum temperature coefficient of 20ppm/°C. It operates within a supply range of VOUT + 0.5V to 36V, drawing a typical supply current of 600µA. The device provides buffered output drive capability of ±10mA with low output impedance. It is housed in an 8-lead hermetic LS8 package and is fully specified for operation from –40°C to 125°C.

Voltage Reference Feature Summary

• Buffered output stage capable of sourcing and sinking ±10mA with precise load regulation
• Hermetic 8-lead LS8 surface mount package providing outstanding long-term stability
• Low noise performance with 1.6ppm peak-to-peak noise in the 0.1Hz to 10Hz band
• Wide input voltage operating range up to 36V with low dropout characteristics

Voltage Reference Applications

• Automotive control and monitoring systems
• High resolution data acquisition systems
• Industrial sensing and process control instrumentation
• Precision regulators requiring high stability

Voltage Reference Procurement Notes

Verify the specific suffix LS8 corresponds to the 8-lead ceramic LCC package when ordering. Confirm the B-grade designation matches the required 20ppm/°C temperature coefficient and ±0.1% accuracy specifications. Ensure the #PBF lead-free finish is compatible with assembly processes. Check automotive qualification requirements if the application demands AEC-Q100 compliance, as standard parts may differ from controlled manufacturing versions.

Voltage Reference Selection Notes

Select this component when high stability and hermetic sealing are required for harsh environments. The LS8 package offers superior thermal and mechanical robustness compared to plastic packages. Verify that the 20ppm/°C drift meets system tolerance limits. Consider the 36V input range for direct connection to higher voltage rails without additional pre-regulation stages.
