LT1236CIS8-5#PBF

Voltage Reference Overview

The LT1236CIS8-5#PBF is a precision shunt voltage reference manufactured by Analog Devices, housed in an 8-lead SOIC package. It delivers a nominal output voltage of 5V with an initial accuracy of ±0.05%. The device features a maximum temperature coefficient of 10 ppm/°C and operates within an industrial temperature range of -40°C to +85°C. It supports both series and shunt modes, sourcing or sinking up to 10mA while maintaining high immunity to input voltage variations.

Voltage Reference Feature Summary

• Combines ultra-low drift and noise characteristics with excellent long-term stability using a buried zener diode structure.
• Capable of operating in either series or shunt mode, providing flexibility for various circuit configurations.
• Features very low noise performance and high ripple rejection to ensure signal integrity in sensitive applications.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'S8' denotes the SOIC-8 package. Confirm the '-5' suffix indicates the 5V output variant. Ensure compatibility with existing PCB footprints for the 8-lead plastic SOIC form factor before integration.

Voltage Reference Selection Notes

Select this component when a stable 5V reference is required across varying temperatures without active heating elements. The industrial grade offers a balance of cost and performance for general-purpose instrumentation. Consider the 10mA current capability for driving moderate loads directly or serving as a reference for external boost circuits.

Voltage Reference Part Context

This part belongs to the LT1236 family of precision references, which are designed to replace older discrete solutions. The family includes variants with different accuracies (A, B, C grades) and packages (PDIP, SOIC). The CIS8 designation specifically identifies the industrial temperature range version in the surface-mount SOIC package.
