LT1027ECN8-5#PBF

Voltage Reference Overview

The LT1027ECN8-5#PBF is a precision series voltage reference IC manufactured by Analog Devices Inc. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.1% and a temperature coefficient of 3 ppm/°C. The device operates within an input voltage range of 8 V to 40 V and draws a maximum supply current of 3.5 mA, with typical operation at 2.2 mA. It supports a maximum load current of 15 mA and functions reliably across a temperature range of 0°C to +70°C. Packaged in an 8-pin PDIP through-hole format, it is designed for applications requiring stable, low-noise voltage references.

Voltage Reference Feature Summary

• Delivers a precise 5 V fixed output with high initial accuracy
• Features ultra-low temperature drift for thermal stability
• Supports high input voltage ranges up to 40 V
• Provides robust load current capability for direct circuit driving

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• High-resolution digital-to-analog converter (DAC) voltage standards
• Calibration equipment requiring stable reference voltages
• Instrumentation systems demanding low drift performance

Voltage Reference Procurement Notes

Verify the specific suffix ECN8-5#PBF to ensure compatibility with through-hole PCB layouts and 5 V output requirements. Confirm that the operating environment remains within the specified 0°C to +70°C range. Check for RoHS compliance status if environmental regulations apply to your assembly process. Ensure input voltage does not exceed the 40 V maximum limit during normal operation or transient conditions.

Voltage Reference Selection Notes

Select this component when a fixed 5 V reference with ±0.1% accuracy is required. Choose the PDIP-8 package for through-hole manufacturing processes. Consider the 3 ppm/°C temperature coefficient for environments with significant thermal variations. Verify that the 15 mA output current meets the load requirements without external buffering.

Voltage Reference Part Context

This part belongs to the LT1027 family of precision voltage references from Analog Devices. The family includes various output voltages and packages, such as SOIC and DIP options. The LT1027 series is known for its buried Zener architecture, which offers superior noise performance and long-term stability compared to standard bandgap references. This specific variant focuses on the 5 V output in a through-hole package.
