LT1236CIN8-10#PBF

Voltage Reference Overview

The LT1236CIN8-10#PBF is a precision voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 10V 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 utilizes an 8-lead PDIP package for through-hole mounting. The reference 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 configurations
• Features a dedicated trim pin for precise output voltage adjustment

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'N8' corresponds to the 8-lead PDIP package and 'I' indicates the industrial temperature grade (-40°C to +85°C). Confirm the '#PBF' designation ensures lead-free compliance. Cross-reference the manufacturer part number LT1236CIN8-10#PBF with official Analog Devices documentation to ensure compatibility with existing circuit designs requiring 10V precision references.

Voltage Reference Selection Notes

Select this component when a 10V precision reference with industrial temperature stability is required. The 'C' grade offers a 10 ppm/°C temperature coefficient, suitable for applications demanding moderate drift performance. Ensure the PCB layout accommodates the PDIP-8 footprint and that input voltage differentials remain within specified limits to maintain regulation accuracy during operation.

Voltage Reference Part Context

This component belongs to the LT1236 family of precision references from Analog Devices. The family includes variants with 5V and 10V outputs, different accuracy grades (A, B, C), and various package options including SOIC and PDIP. The LT1236 is designed as a drop-in replacement for older standards like the AD586 and AD587, offering improved noise and stability characteristics without on-chip heaters.

Voltage Reference FAQ

Can the LT1236CIN8-10#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?

The TRIM pin allows for adjusting the output voltage. For the 10V version, it has an impedance of about 12kΩ and a nominal open-circuit voltage of 5V, enabling fine-tuning of the output.
