LT1236AIS8-5#PBF

Voltage Reference Overview

The LT1236AIS8-5#PBF is a precision shunt voltage reference manufactured by Analog Devices, housed in an 8-lead plastic SOIC package. It delivers a nominal output voltage of 5V with a maximum initial accuracy of 0.05%. The device features an ultra-low temperature coefficient of 2ppm/°C and operates within an industrial temperature range of -40°C to +85°C. It supports both sourcing and sinking currents up to 10mA, maintains high ripple rejection, and requires a minimum input-to-output differential of 1V.

Voltage Reference Feature Summary

• Combines buried zener diode structure for low noise and superior long-term stability without on-chip heaters
• Capable of sourcing and sinking load currents up to 10mA while maintaining regulation
• Offers high immunity to input voltage variations with minimal thermal regulation effects

Voltage Reference Applications

• A/D and D/A converters
• Precision regulators
• Inertial navigation systems
• Digital voltmeters

Voltage Reference Procurement Notes

Verify the specific suffix AIS8 against the official datasheet to confirm the industrial temperature grade (-40°C to +85°C) and SOIC-8 package type. Ensure compatibility with system requirements for shunt mode operation and current limits. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Voltage Reference Selection Notes

Select this component when high accuracy and low drift are critical for system performance over wide temperature variations. The industrial grade variant suits applications requiring reliability beyond standard commercial ranges. Consider the 10mA current capability for driving moderate loads directly or serving as a stable reference for external boost circuits.

Voltage Reference Part Context

Part of the LT1236 family of precision references utilizing subsurface zener technology. This architecture provides better temperature drift and time stability compared to band-gap references. The series includes various accuracy grades and packages, with the 'A' grade offering the tightest specifications for temperature coefficient and initial accuracy.

Voltage Reference Replacement Considerations

Pin-compatible with AD586 and AD586 equivalents. Verify electrical parameters such as temperature coefficient and current limits match application needs before substitution.
