LT1236BIN8-10#PBF

Voltage Reference Overview

The LT1236BIN8-10#PBF is a precision voltage reference from Analog Devices, manufactured by Linear Technology Corporation. It utilizes a buried zener diode structure to achieve ultra-low drift and noise with excellent long-term stability. The device provides a nominal output of 10V and operates in both series and shunt modes. Key electrical characteristics include a maximum temperature coefficient of 5ppm/°C and an initial accuracy of ±0.05%. It features high ripple rejection and low supply current. The component is housed in an 8-lead PDIP package (N8) and supports an industrial operating temperature range.

Voltage Reference Feature Summary

• Utilizes a buried zener diode structure for superior noise performance and time stability compared to surface breakdown devices.
• Capable of sourcing and sinking up to 10mA of output current while maintaining regulation.
• Operates effectively in both series and shunt configurations with minimal thermal regulation effects.
• Pin-compatible with legacy AD586 and AD587 references.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix BIN8 corresponds to the 8-lead PDIP package and industrial temperature grade when ordering. Confirm that the #PBF designation indicates lead-free compliance. Ensure the input voltage differential remains within specified limits during operation. Check for any recent product change notices regarding manufacturing location or material composition before finalizing procurement.

Voltage Reference Selection Notes

Select this component for applications requiring high precision without the complexity of on-chip heaters. The 10V output version allows for flexible configuration as a shunt regulator with two-terminal Zener characteristics. Consider the trim pin functionality if fine-tuning the output voltage is necessary for system calibration. Evaluate the package size constraints against the available DIP footprint options.

Voltage Reference Part Context

The LT1236 series represents a family of precision references designed to combine low drift with high accuracy. The BIN8 variant specifically denotes the industrial temperature range (-40°C to +85°C) and the through-hole PDIP packaging. This part belongs to the broader LT1236 line, which also includes SOIC packages and different temperature grades like AC and BC.

Voltage Reference Replacement Considerations

The datasheet explicitly states pin compatibility with AD586 and AD587. These legacy parts can be considered direct replacements in existing designs where pinout matching is critical. Verify that the replacement part meets the specific temperature coefficient and accuracy requirements of the original design.
