LT6656AILS8-1.25

Voltage Reference Overview

The LT6656AILS8-1.25 is a precision series voltage reference manufactured by Analog Devices Inc., housed in an 8-lead hermetic Leadless Chip Carrier (LCC) package. It provides a fixed output voltage of 1.25V with an initial accuracy of 0.05% and a maximum temperature coefficient of 10ppm/°C. The device draws less than 1µA of supply current, operates within a supply range up to 18V, and supports a minimum output capacitance of 1µF for stability.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for battery-powered applications
• High accuracy with low temperature drift characteristics
• Capable of sourcing high output drive current
• Hermetic packaging ensures long-term stability without humidity sensitivity

Voltage Reference Applications

• Precision A/D and D/A converters
• Portable gas monitors
• Battery- or solar-powered systems
• Micropower remote sensing

Voltage Reference Procurement Notes

Verify the specific LS8 package variant when ordering, as it differs from standard plastic packages. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing process. Ensure the supplier provides valid traceability documentation for the hermetic ceramic package. Check for any specific handling instructions related to the leadless chip carrier format during assembly.

Voltage Reference Selection Notes

Select this part when extreme long-term stability and hermetic sealing are required compared to plastic alternatives. The LS8 package offers superior protection against environmental factors like humidity. Consider the higher cost associated with hermetic packaging versus standard SOT-23 or DFN options. Verify that the 1.25V output aligns with your system's reference voltage needs.

Voltage Reference Part Context

This component belongs to the LT6656 family of micropower precision voltage references. The LS8 suffix indicates the 8-lead hermetic LCC package, distinct from the plastic TSOT-23 or DFN variants. It shares core electrical specifications with other grades but emphasizes stability through its specialized packaging technology designed for harsh environments.
