LT1236ACN8-5#PBF

Voltage Reference Overview

The LT1236ACN8-5#PBF is a precision shunt voltage reference manufactured by Analog Devices Inc., housed in an 8-pin PDIP package. It provides a fixed output voltage of 5 V with an initial accuracy of 0.05% and a temperature coefficient of 10 PPM/°C. The device operates within a supply voltage range up to 40 V and supports a maximum shunt current of 10 mA. Quiescent current is typically 800 uA, with a maximum of 1.5 mA. It functions without a shutdown feature across a commercial temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

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

Voltage Reference Applications

• High-precision data acquisition systems
• Calibration equipment requiring stable reference voltages
• Industrial process control instrumentation

Voltage Reference Procurement Notes

Verify the specific suffix ACN8 against the official datasheet to confirm the PDIP-8 package and commercial temperature grade. Confirm RoHS compliance status via the manufacturer's documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Voltage Reference Selection Notes

Select this component when a through-hole PDIP package is required for board layout constraints. Choose the AC grade for commercial temperature applications where 10 PPM/°C drift is acceptable. Ensure input voltage remains within the 40 V limit and power dissipation limits are respected at the maximum 10 mA shunt current.

Voltage Reference Part Context

This part belongs to the LT1236 series of precision references, which are designed to replace older discrete Zener solutions. The series offers pin compatibility with legacy parts like the AD586 and AD587, facilitating direct upgrades in existing designs that require improved stability and lower noise characteristics.

Voltage Reference Replacement Considerations

LT1236BCN8-5#PBF (Better accuracy/tempco), LT1236CCN8-5#PBF (Commercial temp, higher tempco). Verify package and electrical specs match requirements.
