LT1236BCN8-5#PBF

Voltage Reference Overview

The LT1236BCN8-5#PBF is a precision voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 5V with an initial accuracy of ±0.05%. The device features a maximum temperature coefficient of 5ppm/°C and operates within an industrial temperature range of 0°C to +70°C. It supports both series and shunt modes, sourcing and sinking up to 10mA. Key electrical parameters include a maximum input voltage of 40V, a quiescent current of 1.2mA (max 1.5mA), and low noise characteristics. The component is housed in an 8-lead PDIP package.

Voltage Reference Feature Summary

• Combines ultra-low drift and noise with excellent long-term stability using a buried zener diode structure.
• Capable of operating in either series or shunt mode while maintaining high precision.
• Features very low noise performance and high ripple rejection for sensitive applications.

Voltage Reference Applications

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status before procurement. Confirm the N8 package designation corresponds to the required 8-lead PDIP form factor for your PCB layout. Ensure the BC grade specifications meet the system's accuracy and drift requirements. Check for any obsolescence notices or lifecycle changes from the manufacturer.

Voltage Reference Selection Notes

Select this part when a 5V precision reference with industrial temperature stability is required. The BC grade offers a balance of 5ppm/°C drift and 0.05% accuracy. Consider the PDIP package if through-hole mounting is necessary. Evaluate the need for series versus shunt operation based on load current requirements and power dissipation constraints.

Voltage Reference Part Context

This component belongs to the LT1236 family of precision references, which are designed for high-performance analog circuits. The family includes variants with different output voltages (5V and 10V) and accuracy grades (A, B, C). The LT1236 is pin-compatible with older AD586 and AD587 references, facilitating upgrades in existing designs.
