LT1236AIS8-10#PBF

Voltage Reference Overview

The LT1236AIS8-10#PBF is a precision voltage reference featuring a buried zener diode structure, providing a nominal output of 10V. It operates within an industrial temperature range of -40°C to +85°C and utilizes an 8-lead plastic SOIC package. The device offers high initial accuracy with a maximum tolerance of ±0.05% and an ultra-low temperature coefficient of 5ppm/°C. It supports both series and shunt modes, sourcing and sinking up to 10mA while maintaining immunity to input voltage variations.

Voltage Reference Feature Summary

• Utilizes a buried zener diode structure for superior long-term stability and low noise compared to surface breakdown devices.
• Capable of operating in both series and shunt configurations without performance degradation.
• Features a dedicated trim pin allowing for precise output voltage adjustment.
• Designed to minimize thermal regulation effects and temperature-induced hysteresis.

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 extended industrial temperature range (-40°C to +85°C) rather than the commercial grade. Confirm the 'S8' designation matches the required 8-lead SOIC footprint. Ensure the '#PBF' indicates lead-free compliance if required by assembly specifications. Cross-reference the datasheet electrical characteristics for line and load regulation limits under your specific operating conditions.

Voltage Reference Selection Notes

Select this component when system accuracy requires minimal drift over wide temperature fluctuations. The buried zener architecture provides better time stability than standard bandgap references. Consider the available trim range if exact voltage calibration is necessary. Evaluate the power dissipation capabilities relative to the ambient environment to ensure operation remains within the specified junction temperature limits.

Voltage Reference Part Context

This part belongs to the LT1236 family of precision references manufactured by Analog Devices. The family includes variants with different accuracies (A, B, C grades) and temperature ranges. The LT1236 is designed as a drop-in replacement for older discrete zener solutions or other precision references like the AD586 and AD587, offering improved noise and stability characteristics in a compact integrated circuit form factor.

Voltage Reference FAQ

Can the LT1236AIS8-10#PBF be used as a two-terminal shunt regulator?

Yes, the 10V version can operate as a shunt regulator (two-terminal Zener) with the same precision characteristics as its three-terminal connection mode.

What is the purpose of the TRIM pin on this device?

The TRIM pin allows for adjusting the output voltage. For the 'A' version, it typically provides a restricted trim range to fine-tune the output to exactly 10.000V while minimizing shifts in the temperature coefficient.
