LT1236AIN8-10#PBF

Voltage Reference Overview

The LT1236AIN8-10#PBF is a precision voltage reference utilizing a buried zener diode structure, housed in an 8-lead PDIP package. It provides a fixed 10V output with a maximum initial accuracy of ±0.05% and a temperature coefficient of 5ppm/°C. The device operates within an industrial temperature range of -40°C to +85°C and supports a maximum input voltage of 40V. It features ultra-low noise characteristics, including 6μVP-P (0.1Hz to 10Hz) and 3.5μVRMS (10Hz to 1kHz), while maintaining long-term stability of 30ppm over 1000 hours.

Voltage Reference Feature Summary

• Combines ultra-low drift and noise with excellent long-term stability and high output accuracy without using on-chip heaters.
• Reference output can both source and sink up to 10mA and is almost totally immune to input voltage variations.
• Based on a buried zener diode structure which eliminates noise and stability problems associated with surface breakdown devices.
• Pin compatible with AD586 and AD587, allowing for direct replacement in existing designs.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'AIN8-10' against official Analog Devices documentation to confirm the exact grade, package type, and voltage rating. Ensure that the industrial temperature range (-40°C to +85°C) aligns with your system requirements. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards and pinout configurations.

Voltage Reference Selection Notes

Select this component when high precision and low drift are critical, particularly for systems requiring stable references over wide temperature ranges. The buried zener technology offers superior time stability compared to band-gap references. Consider the trim pin functionality if fine-tuning the output voltage is necessary for specific application tolerances.

Voltage Reference Part Context

The LT1236 series represents a family of precision voltage references designed by Linear Technology (now Analog Devices). It bridges the performance gap between standard band-gap references and more complex regulated references. The 'A' grade denotes tighter initial accuracy specifications, while the 'I' suffix indicates the extended industrial temperature range capability.

Voltage Reference FAQ

Can the LT1236AIN8-10#PBF be used as a shunt regulator?

Yes, the 10V version can be used as a shunt regulator (two-terminal zener) with the same precision characteristics as the three-terminal connection.

What is the purpose of the TRIM pin on the LT1236-10?

The TRIM pin allows for adjusting the output voltage. For the 'A' version, it provides a restricted trim range of approximately ±10mV to set the output precisely to 10.000V.
