LTC6655CHLS8-5

Overview

The LTC6655CHLS8-5 is a precision bandgap voltage reference from Analog Devices, featuring a 5V output with ±0.05% initial accuracy and a maximum temperature coefficient of 5ppm/°C. It operates within a –40°C to 125°C range and utilizes an 8-lead hermetic LS8 package. Key electrical specifications include a low dropout of 500mV, supply current under 7.5mA, and shutdown current below 20µA. The device offers superior load regulation and line rejection, ensuring stable performance across wide operating conditions.

Feature Summary

• Hermetic 5mm × 5mm LS8 package provides outstanding stability and immunity to humidity sensitivity
• Advanced curvature compensation achieves low drift with predictable temperature characteristics
• Capable of sourcing and sinking up to ±5mA for versatile load driving requirements
• Includes a dedicated shutdown mode for significant power reduction in low-power applications

Applications

• Instrumentation and test equipment requiring high resolution measurements
• High resolution data acquisition systems demanding precise voltage references
• Precision battery monitors and weigh scales
• Medical equipment and precision regulators

Procurement Notes

Verify the specific ordering suffix to confirm the LS8 hermetic package variant. Ensure compatibility with the required output voltage and accuracy grade. Confirm that the supplier provides official documentation for the hermetic seal integrity. Check for any specific handling requirements associated with ceramic leadless chip carrier packages during assembly.

Selection Notes

Select this component when long-term stability and humidity resistance are critical. The LS8 package is preferred over MSOP for harsh environments due to its hermetic nature. Consider the 5ppm/°C drift specification against system calibration needs. Evaluate the need for sink capability if the application involves dynamic load variations or bidirectional current flow.

Part Context

This part belongs to the LTC6655 family of precision references, designed for high-performance analog signal chains. The CH designation indicates a specific accuracy and drift grade within the series. The LS8 package distinguishes it from standard plastic MSOP variants by offering enhanced environmental protection and lower long-term drift, making it suitable for demanding industrial and automotive applications.
