LT1236ACS8-5#PBF

Voltage Reference Overview

The LT1236ACS8-5#PBF is a precision voltage reference manufactured by Analog Devices Inc., housed in an 8-lead plastic SOIC package. It provides a fixed output voltage of 5V with an initial accuracy of ±0.05%. The device operates within an industrial temperature range of 0°C to +70°C and features a maximum temperature coefficient of 5ppm/°C. It supports a maximum shunt current of 10mA and functions with a supply voltage up to 40V, drawing a typical quiescent current of 800µA.

Voltage Reference Feature Summary

• Utilizes a buried zener diode structure for superior long-term stability and low noise compared to surface breakdown devices.
• Capable of sourcing and sinking up to 10mA of current while maintaining high precision.
• Designed to minimize thermal regulation effects and temperature-induced hysteresis without on-chip heaters.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'S8' corresponds to the SOIC-8 package and '#PBF' indicates lead-free compliance before ordering. Confirm that the AC grade meets the required 5ppm/°C drift specification for your application environment. Ensure input voltage differentials remain within safe operating limits during procurement planning.

Voltage Reference Selection Notes

Select this component when ultra-low drift and high accuracy are critical for system performance. The AC grade offers a tighter temperature coefficient than C-grade alternatives. Consider the SOIC-8 footprint constraints and verify that the 10mA current capability suffices for the intended load requirements.

Voltage Reference Part Context

This part belongs to the LT1236 family of precision references, which includes 5V and 10V variants. The LT1236 series is designed to replace older components like the AD586 and AD587 due to pin compatibility. It serves as a high-performance solution for applications requiring stable reference voltages over varying temperatures.
