LT1236BCS8-10#PBF

Voltage Reference Overview

The LT1236BCS8-10#PBF is a precision shunt voltage reference manufactured by Analog Devices Inc. housed in an 8-lead SOIC package. It provides a nominal output voltage of 10 V with a maximum initial accuracy of 0.05%. The device features a maximum temperature coefficient of 5 ppm/°C and operates within an industrial temperature range from 0°C to +70°C. It supports a maximum input voltage of 40 V, with a typical operating supply current of 800 µA and a maximum of 1.5 mA. The output can source or sink up to 10 mA.

Voltage Reference Feature Summary

• Utilizes a buried zener diode structure for superior noise performance and long-term stability compared to surface breakdown devices.
• Capable of operating in both series and shunt modes while maintaining high precision characteristics.
• Features extremely low thermal regulation effects and minimized temperature-induced hysteresis.
• Includes a dedicated trim pin on the 10V version to allow for precise output voltage adjustment.

Voltage Reference Applications

• High-resolution A/D and D/A converters
• Precision regulators and instrumentation systems
• Inertial navigation systems requiring stable references
• Digital voltmeters and precision scales

Voltage Reference Procurement Notes

Verify the specific suffix 'CS8' corresponds to the 8-lead plastic SOIC package configuration required for your PCB layout. Confirm that the 'B' grade designation meets the necessary 0.05% accuracy and 5 ppm/°C temperature coefficient specifications for your application environment. Ensure the industrial temperature range of 0°C to +70°C aligns with your operational requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this component when ultra-low drift and high accuracy are critical without the complexity of heater-based references. The 10V output variant offers a trim pin for fine-tuning, unlike the 5V version which requires specific external networks to maintain temperature coefficient stability during trimming. Consider the SOIC package for surface-mount assembly needs and verify that the minimum input-to-output differential of 1V is maintained in your circuit design.

Voltage Reference Part Context

This part belongs to the LT1236 family of precision references, which combines low drift with excellent long-term stability. The family includes variants with different output voltages (5V and 10V), accuracy grades (A, B, C), and package options including PDIP and SOIC. The LT1236 is designed as a drop-in replacement for older generation references like the AD586 and AD587, offering improved performance metrics in a compact form factor.
