LT1027DCN8-5#PBF

Voltage Reference Overview

The LT1027DCN8-5#PBF is a precision series voltage reference from Analog Devices, housed in an 8-pin PDIP package. It delivers a fixed 5 V output with an initial accuracy of 0.05% and a temperature coefficient of 2 PPM/°C. The device operates within a supply voltage range of up to 40 V and draws a typical working current of 2.2 mA, with a maximum of 3.5 mA. It supports a shunt current between 2.2 mA and 15 mA, functioning reliably across a temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Provides high-precision voltage regulation with low temperature drift characteristics
• Features a buried Zener architecture for superior noise performance
• Capable of sourcing significant load current while maintaining stability

Voltage Reference Applications

• High-resolution analog-to-digital converter (ADC) references
• Precision digital-to-analog converter (DAC) excitation sources
• Calibration equipment requiring stable voltage standards

Voltage Reference Procurement Notes

Verify the specific suffix DCN8 against your schematic requirements to ensure compatibility with through-hole mounting and the desired accuracy grade. Confirm that the operating environment remains within the specified 0°C to +70°C range. Check for any recent Product Change Notifications regarding package or material updates before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a fixed 5 V reference with exceptional long-term stability and low drift is required. The PDIP-8 package suits prototyping and applications where surface-mount space is not constrained. Ensure the input voltage exceeds the dropout requirement and that thermal dissipation remains within limits for the chosen enclosure.

Voltage Reference Part Context

This part belongs to the LT1027 family of precision voltage references, known for their robust design and low noise. The 'DC' designation indicates the commercial temperature grade and specific accuracy bin, while 'N8' specifies the PDIP-8 package style. It serves as a critical reference element in mixed-signal systems demanding high line and load regulation.
