LT1236CIS8-10#PBF

Voltage Reference Overview

The LT1236CIS8-10#PBF is a precision voltage reference from Analog Devices, featuring a buried zener diode structure for low noise and high stability. It provides a nominal output of 10V with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. The device operates in series or shunt modes, sourcing and sinking up to 10mA. It functions within an industrial temperature range of -40°C to +85°C using an 8-lead SOIC package.

Voltage Reference Feature Summary

• Utilizes a buried zener diode structure to minimize noise and enhance long-term stability compared to surface breakdown devices.
• Capable of operating in both series and shunt configurations while maintaining high precision characteristics.
• Features a dedicated trim pin allowing for precise adjustment of the output voltage.

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 industrial temperature range (-40°C to +85°C) and 'S8' indicates the SOIC-8 package. Confirm the '#PBF' designation ensures lead-free compliance. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure authenticity and correct revision level before integration into designs.

Voltage Reference Selection Notes

Select this component when a 10V precision reference with industrial temperature stability is required. The 'C' grade offers a balance of accuracy and cost, suitable for applications where 10ppm/°C drift is acceptable. Ensure input voltage differential remains above 1V and consider thermal management if operating near current limits.

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 includes variants with different accuracies (A, B, C grades) and temperature ranges (Commercial, Industrial). The LT1236-10 specifically denotes the 10V output version.

Voltage Reference FAQ

Can the LT1236CIS8-10#PBF operate as a shunt regulator?

Yes, the device can be used 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 the LT1236-10?

The TRIM pin allows for adjusting the output voltage. It has an impedance of about 12kΩ and is designed to be driven from a source impedance of 3kΩ or less to minimize changes in the temperature coefficient during trimming.
