LT1460EIS8-5#PBF

Voltage Reference Overview

The LT1460EIS8-5#PBF is a micropower precision series voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 5V with an initial accuracy tolerance of ±0.125%. The device operates within the industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 20ppm/°C. Electrical specifications include a maximum supply current of 225µA, a minimum output sourcing current capability of 20mA, and a maximum input voltage rating of 30V.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors for high accuracy and low drift
• Operates stably with capacitive loads without requiring external output compensation capacitors
• Provides reverse battery protection to prevent damage from incorrect polarity connections

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• High-accuracy digital-to-analog converter (DAC) references
• Handheld instrumentation systems
• Precision regulator circuits

Voltage Reference Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the package marking matches the specified part number and temperature grade. Ensure compliance with RoHS directives and check for any specific handling requirements related to electrostatic discharge during storage and assembly processes.

Voltage Reference Selection Notes

Select this component when an industrial-grade voltage reference with a 5V output is required. The SOIC-8 package is suitable for surface-mount applications where board space is limited. Consider the 20mA output drive capability and low quiescent current for power-sensitive designs. Verify that the system input voltage remains within the specified operational limits relative to the output voltage.

Voltage Reference Part Context

This component belongs to the LT1460 family of micropower bandgap references. The 'EI' designation indicates the industrial temperature grade (-40°C to +85°C) and the specific accuracy class. The 'S8' suffix denotes the 8-lead plastic SOIC package. This family combines low power dissipation advantages over shunt references with high precision suitable for demanding measurement applications.
