LTC1069-6CS8#TRPBF

Overview

The LTC1069-6CS8#TRPBF is a precision, low-power voltage reference IC manufactured by Analog Devices Inc. It belongs to the LTC1069 family and is housed in an 8-pin SOIC package. The device provides a fixed output voltage of 2.5V with high accuracy and low temperature drift. It operates from a supply voltage range of 2.7V to 36V and draws a typical quiescent current of 40µA. Key electrical characteristics include an initial accuracy of ±0.1% and a temperature coefficient of 3ppm/°C. The component is designed for applications requiring stable reference voltages in battery-powered and industrial systems.

Feature Summary

• Provides a fixed 2.5V output voltage with high precision
• Features low temperature drift for stable performance across operating ranges
• Operates efficiently with low quiescent current consumption
• Supports wide input supply voltage ranges

Applications

• Battery-powered instrumentation systems
• Precision data acquisition circuits
• Industrial process control references
• Medical equipment power supplies

Procurement Notes

Verify the complete part number including suffixes such as TRPBF against official Analog Devices documentation to ensure correct packaging and lead-free compliance. Confirm RoHS status and specific lot traceability requirements with authorized distributors prior to ordering. Check for any regional distribution restrictions or alternative package options if standard availability is limited.

Selection Notes

Select this component when a fixed 2.5V reference with ±0.1% initial accuracy is required. Ensure the input voltage remains within the 2.7V to 36V range. Consider thermal management if operating near maximum temperature limits. Verify that the 40µA quiescent current aligns with system power budget constraints compared to higher precision alternatives.

Part Context

This part is part of the LTC1069 series of micropower voltage references. It shares architectural similarities with other members like the LTC1069-1 and LTC1069-5 but differs in its fixed 2.5V output setting. The CS8 suffix indicates the commercial temperature range and SOIC-8 package type. It serves as a stable reference source for ADCs and DACs in signal conditioning chains.

Replacement Considerations

Direct substitutes may include other LTC1069 variants with different output voltages if circuit scaling is possible. Cross-reference with LM4040 or REF50xx series for pin-compatible alternatives, though accuracy and drift specifications may differ. Verify thermal performance and load regulation characteristics before swapping.
