LT1027DCLS8-5

Voltage Reference Overview

The LT1027DCLS8-5#PBF is a precision hermetic voltage reference in an 8-pin LCC package. It provides a fixed 5V output with ±0.10% maximum initial accuracy and a maximum temperature coefficient of 5ppm/°C. The device operates on supply voltages from 8V to 40V, sourcing up to 15mA and sinking up to 10mA. It features low noise performance below 1ppm peak-to-peak (0.1Hz to 10Hz) and excellent long-term stability of 12ppm at 1000 hours. Designed for the commercial temperature range of 0°C to 70°C.

Voltage Reference Feature Summary

• Hermetic leadless chip carrier package ensures immunity to humidity and superior thermal hysteresis performance.
• Buried Zener diode structure enables extremely low noise and high long-term stability compared to bandgap references.
• Capable of sourcing 15mA and sinking 10mA while maintaining constant output across wide input voltage variations.

Voltage Reference Applications

• Instrumentation and test equipment
• High resolution data acquisition systems
• A/D and D/A converters
• Precision regulators

Voltage Reference Procurement Notes

Verify the specific suffix 'D' confirms the 0°C to 70°C operating range. Confirm the LS8 package type matches the required footprint. Ensure the '#PBF' designation aligns with lead-free procurement requirements. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity before ordering.

Voltage Reference Selection Notes

Select this component when hermetic sealing is required to prevent humidity-induced drift. Choose over plastic packages if thermal hysteresis specifications are critical for the application environment. Consider the 8V minimum supply requirement and verify that the load current stays within the 15mA source and 10mA sink limits for optimal regulation.

Voltage Reference Part Context

This part belongs to the LT1027LS8 family, which offers performance similar to the standard LT1027 but housed in a compact 5mm × 5mm hermetic ceramic package. It serves as a modern alternative to larger through-hole metal can references like the LT1021, providing comparable stability in a surface-mount compatible form factor.
