LT1236CCS8-5#TRPBF

Voltage Reference Overview

The LT1236CCS8-5#TRPBF is a precision voltage reference from Analog Devices, featuring a buried zener diode structure for low noise and high stability. It provides a nominal output of 5V with a maximum initial accuracy of 0.05%. The device operates in an industrial temperature range of 0°C to 70°C and exhibits a maximum temperature coefficient of 15ppm/°C. Packaged in an 8-lead plastic SOIC (S8), it supports both series and shunt modes with input voltages up to 40V.

Voltage Reference Feature Summary

• Combines ultra-low drift and noise with excellent long-term stability using a buried zener diode structure.
• Capable of sourcing and sinking up to 10mA while maintaining high output accuracy.
• Operates effectively in both series and shunt configurations with minimal thermal regulation effects.

Voltage Reference Applications

• A/D and D/A Converters
• Precision Regulators
• Inertial Navigation Systems

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the CC grade specifications against design requirements, as they differ from higher precision grades. Ensure the industrial temperature range meets the operational environment constraints before finalizing procurement.

Voltage Reference Selection Notes

Select this component for applications requiring a stable 5V reference without the need for military-grade temperature ranges. Consider the CC grade if cost is a factor but verify that the 15ppm/°C temperature coefficient meets system accuracy budgets. Evaluate the S8 package suitability for the intended PCB layout and thermal management strategy.

Voltage Reference Part Context

This part belongs to the LT1236 family of precision references, which are designed to replace older technologies like surface breakdown devices. The family offers various voltage outputs and accuracy grades, utilizing a subsurface zener architecture for superior time stability compared to standard band-gap references.

Voltage Reference Replacement Considerations

Pin-compatible replacements include AD586 and AD586 variants. Verify electrical characteristics such as temperature coefficient and noise levels match the original design requirements before substitution.
