LT1236CIN8-5#PBF

Voltage Reference Overview

The LT1236CIN8-5#PBF is a precision voltage reference from Analog Devices, featuring a 5V output with an initial accuracy of ±0.05% and a maximum temperature coefficient of 15ppm/°C. It operates within an industrial temperature range of -40°C to +85°C and utilizes an 8-lead PDIP package. The device supports both series and shunt modes, sourcing and sinking up to 10mA while maintaining high ripple rejection.

Voltage Reference Feature Summary

• Combines ultra-low drift and noise with excellent long-term stability using a buried zener diode structure.
• Capable of operating in either series or shunt mode with high immunity to input voltage variations.
• Features a trim pin for precise output voltage adjustment while minimizing temperature coefficient shifts.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'I' indicates the extended industrial temperature range (-40°C to +85°C) compared to the standard commercial grade. Confirm the 'N8' designation corresponds to the 8-lead PDIP package. Ensure the '#PBF' suffix denotes lead-free and RoHS compliance as per manufacturer specifications before finalizing procurement.

Voltage Reference Selection Notes

Select this component when low drift and high accuracy are critical for system performance over varying temperatures. The industrial grade ensures reliability in broader thermal environments compared to commercial variants. Consider the shunt capability if space for a separate regulator is limited, noting the minimum input-output differential requirements for stable operation.

Voltage Reference Part Context

This part belongs to the LT1236 family of precision references, which are designed to replace older standards like the AD586 and AD587 due to pin compatibility. The family offers both 5V and 10V outputs, utilizing a subsurface zener technology that provides superior temperature drift and time stability compared to standard band-gap references.

Voltage Reference FAQ

Can the LT1236CIN8-5#PBF operate in shunt mode?

Yes, the device can be used as a shunt regulator (two-terminal zener) with the same precision characteristics as its three-terminal series connection.

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

The TRIM pin allows for adjusting the output voltage. For the 5V version, it requires specific external circuitry to maintain minimal shifts in the output temperature coefficient during trimming.
