LTC6655BHMS8-2.048#TRPBF

Overview

The LTC6655BHMS8-2.048#TRPBF is a precision bandgap voltage reference delivering a fixed 2.048V output with an initial accuracy of ±0.025% and a maximum temperature coefficient of 2ppm/°C. It operates within a –40°C to 125°C range, featuring low dropout capability of 500mV and a maximum supply voltage of 13.2V. The device provides source and sink currents up to ±5mA, includes a shutdown mode drawing less than 20µA, and is housed in an 8-lead MSOP package.

Feature Summary

• Advanced curvature compensation ensures predictable temperature characteristics and high accuracy.
• Superior load regulation with both source and sink current capabilities maintains performance across varying conditions.
• Low power shutdown mode significantly reduces consumption for energy-efficient applications.

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the B-grade designation matches the required ±0.025% initial accuracy specification. Ensure the 8-lead MSOP package form factor aligns with the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component for designs requiring stable reference voltages without frequent calibration. The low drift characteristic simplifies thermal management in wide temperature environments. Consider the 500mV dropout requirement against available supply rails to ensure proper operation under all load conditions.

Part Context

This part belongs to the LTC6655 family of precision references, which also includes options like the LTC6655LN for lower noise specifications. The family offers various output voltages and packages, including hermetic LS8 versions. This specific model represents the standard plastic MSOP variant optimized for general high-precision industrial use.

Replacement Considerations

Direct substitutes include other LTC6655 variants with different output voltages or accuracy grades, such as the LTC6655CHMS8-2.048. Cross-referencing pin compatibility and thermal performance is essential when considering alternative manufacturers' precision references.
