LTC6655BHLS8-2.5

Overview

The LTC6655BHLS8-2.5 is a precision bandgap voltage reference offering an output of 2.5V with ±0.025% initial accuracy and a maximum temperature coefficient of 2ppm/°C. It operates within a supply range up to 13.2V, providing source and sink currents of ±5mA. The device features low noise (0.25ppm P-P from 0.1Hz to 10Hz) and exceptional long-term stability (20ppm/√kHr). Packaged in a hermetic 8-lead LS8 ceramic LCC (5mm × 5mm), it ensures high reliability across the –40°C to 125°C operating temperature range.

Feature Summary

• Hermetic 8-lead LS8 package provides outstanding stability and immunity to humidity sensitivity.
• Advanced curvature compensation achieves low drift of less than 2ppm/°C with predictable temperature characteristics.
• Superior load regulation with both source and sink capabilities ensures consistent performance under varying conditions.

Applications

• Instrumentation and test equipment
• High resolution data acquisition systems
• Precision battery monitors

Procurement Notes

Verify the specific ordering suffix and package type when sourcing. Confirm that the LS8 variant is strictly supplied in trays rather than tape and reel formats. Ensure compatibility with the required thermal management specifications for the hermetic ceramic package during integration.

Selection Notes

Select this component for applications requiring minimal calibration due to high accuracy and low drift. The hermetic LS8 package is ideal for harsh environments where humidity resistance and long-term stability are critical. Consider the shutdown current requirements if power conservation is necessary.

Part Context

This part belongs to the LTC6655 family of precision references, which includes MSOP plastic variants. The LS8 designation specifically denotes the 5mm × 5mm leadless chip carrier package. This hermetic option offers superior long-term drift and hysteresis performance compared to standard plastic packages.
