LT1236BILS8-5#PBF

Voltage Reference Overview

The LT1236BILS8-5#PBF is a precision, low noise, low profile hermetic voltage reference manufactured by Analog Devices. It utilizes a buried Zener diode structure to achieve high output accuracy and excellent long-term stability. The device operates within a supply voltage range of 7.2V to 40V and features an 8-pin LS8 package measuring 5mm × 5mm × 1.5mm. Key electrical specifications include a nominal output voltage of 5V with a maximum initial accuracy of ±0.10% and a temperature coefficient of 10ppm/°C. It supports sourcing and sinking currents up to 10mA while maintaining constant performance against input voltage variations.

Voltage Reference Feature Summary

• Hermetic 5mm × 5mm LCC leadless chip carrier package provides outstanding humidity resistance and thermal hysteresis performance.
• Buried Zener diode structure enables superior time stability and extremely low noise performance compared to standard bandgap references.
• Capable of both sourcing and sinking up to 10mA output current while remaining constant with input voltage variations.

Voltage Reference Applications

• Instrumentation and Test Equipment
• High Resolution Data Acquisition Systems
• A/D and D/A Converters
• Precision Regulators
• Digital Voltmeters

Voltage Reference Procurement Notes

Verify the specific B-grade temperature coefficient (10ppm/°C) and ±0.10% initial accuracy requirements against system error budgets. Confirm that the 8-pin ceramic LS8 package dimensions fit the PCB footprint. Ensure the operating environment does not exceed the specified 40V maximum input voltage or the -40°C to 85°C temperature range. Check for potential IR reflow shifts if soldering processes are utilized.

Voltage Reference Selection Notes

Select this component when high stability in humid environments is required due to its hermetic packaging. It serves as a compact alternative to larger through-hole metal can references like the LT1021. Consider the 10ppm/°C drift specification for applications where tighter tolerance than the A-grade version is acceptable. Verify that the 7.2V minimum supply voltage aligns with the system power architecture.

Voltage Reference Part Context

This part belongs to the LT1236LS8 family of precision voltage references. It shares the same core buried Zener technology and hermetic LS8 package form factor as other variants in the series, such as the LT1236AILS8-5#PBF. The primary distinction lies in the grade-specific performance metrics, specifically the temperature coefficient and initial accuracy tolerances defined for the B-grade classification.
