LT1236AILS8-5#PBF

Voltage Reference Overview

The LT1236AILS8-5#PBF is a hermetic precision voltage reference in an 8-pin, 5mm × 5mm × 1.5mm LCC package. It provides a nominal 5V output with an initial accuracy of ±0.05% and a maximum temperature coefficient of 5ppm/°C. The device operates on a supply voltage from 7.2V to 40V with a typical supply current of 0.8mA. It features low noise performance of less than 1ppm peak-to-peak (0.1Hz to 10Hz) and can source or sink up to 10mA. The operating temperature range is –40°C to +85°C.

Voltage Reference Feature Summary

• Hermetic leadless chip carrier package ensures outstanding humidity resistance and thermal hysteresis stability.
• Buried Zener diode structure enables excellent long-term stability and extremely low noise performance.
• Capable of sourcing and sinking up to 10mA while maintaining constant output despite 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 LS8 hermetic package designation and A-grade temperature coefficient when sourcing replacements. Confirm that the ordering suffix #PBF indicates lead-free finish and tray packaging as specified by Analog Devices. Ensure the application environment does not exceed the absolute maximum ratings for input voltage or power dissipation.

Voltage Reference Selection Notes

Select this component for applications requiring high stability in humid environments where traditional plastic packages may fail. The hermetic construction offers superior protection against environmental stress compared to standard SOIC or DIP variants. Consider the 5mm × 5mm footprint as a compact alternative to larger through-hole metal can references like the LT1021.

Voltage Reference Part Context

This part belongs to the LT1236LS8 family of precision, low-noise, low-profile hermetic voltage references. It shares the same internal buried Zener architecture as other LT1236 variants but utilizes a specialized ceramic leadless chip carrier package designed to minimize thermal hysteresis and humidity sensitivity.
