LT1460EIS8-2.5#TRPBF

Voltage Reference Overview

The LT1460EIS8-2.5#TRPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in an 8-lead plastic SO package with tape and reel packaging. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.125%. The device operates within an industrial temperature range of –40°C to +85°C and features a maximum temperature coefficient of 20ppm/°C over the full operating range. Electrical specifications include a maximum supply current of 130µA for the 2.5V version, 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 precision thin-film resistors to achieve high output accuracy and low drift.
• Designed for stability with capacitive loads without requiring an external output compensation capacitor.
• Incorporates reverse battery protection that prevents current conduction during reverse connections.

Voltage Reference Applications

• Handheld Instruments
• Precision Regulators
• A/D and D/A Converters
• Power Supplies

Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube or cut tape formats. Ensure the 'EI' designation matches the required industrial temperature grade (–40°C to +85°C) and the 0.125% accuracy class for your design specifications. Confirm lead-free finish compliance if RoHS requirements are mandatory for the target assembly process.

Voltage Reference Selection Notes

Select this component when an industrial temperature range is required alongside high precision. The 8-lead SO package offers a surface-mount solution suitable for space-constrained designs. Consider the 20mA output current capability against load requirements and verify that the 20ppm/°C temperature coefficient meets the system's long-term stability needs compared to higher-grade options.

Voltage Reference Part Context

This part belongs to the LT1460 Micropower Precision Series Reference Family from Analog Devices. The family includes various packages such as MSOP, PDIP, TO-92, and SOT-23, offering different accuracy grades and temperature ranges. The LT1460 series is designed to replace older shunt references, providing significant power dissipation advantages while maintaining high performance in compact form factors.
