LT1236CIS8-5#TRPBF

Voltage Reference Overview

The LT1236CIS8-5#TRPBF is a precision shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 5V 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 supports a maximum shunt current of 10mA and accepts input voltages up to 40V. The component is housed in an 8-lead SOIC surface-mount package.

Voltage Reference Feature Summary

• Combines ultra-low drift and noise with excellent long-term stability using a buried zener diode structure.
• Capable of sourcing and sinking up to 10mA while maintaining high output accuracy.
• Operates effectively in both series and shunt modes with minimal thermal regulation effects.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific ordering suffix against official documentation, as it dictates the package type and shipping format. Confirm that the industrial temperature grade (I) matches the operational environment requirements. Ensure compatibility with the target PCB footprint for the SOIC-8 package before finalizing procurement decisions.

Voltage Reference Selection Notes

Select this component when low drift and high accuracy are critical for system performance. The industrial temperature range suits applications requiring operation between -40°C and +85°C. Consider the shunt mode capability if a two-terminal regulator configuration is preferred over a three-terminal series setup.

Voltage Reference Part Context

This part belongs to the LT1236 family of precision references, which utilizes a subsurface zener design for superior temperature drift and time stability compared to standard band-gap references. The 'C' designation indicates a specific accuracy and temperature coefficient tier within the product line, distinct from the higher-performance 'A' or 'B' grades.
