LT1460GIZ-2.5#PBF

Voltage Reference Overview

The LT1460GIZ-2.5#PBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in a 3-lead TO-92 plastic package. It provides a nominal output voltage of 2.5V with an initial accuracy tolerance of ±0.25%. The device operates within an industrial temperature range from -40°C to +85°C and features a maximum temperature coefficient of 25ppm/°C. It supports a minimum output sourcing current of 20mA and maintains a low supply current of approximately 130µA for the 2.5V variant.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors to achieve high output accuracy and low drift.
• Capable of supplying up to 20mA of load current while maintaining excellent line regulation characteristics.
• Operates stably with capacitive loads without requiring an external output compensation capacitor.
• Includes 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 suffix 'GIZ' corresponds to the TO-92 package and industrial temperature grade (-40°C to +85°C). Confirm the '#PBF' designation indicates lead-free finish compliance. Ensure the ordering code matches the required 2.5V output option, as other voltage variants exist within the same family.

Voltage Reference Selection Notes

Select this component when an industrial temperature range is required alongside a through-hole TO-92 package form factor. It is suitable for applications demanding stable precision references where board space allows for larger packages compared to surface-mount alternatives. Consider the 25ppm/°C drift specification against tighter requirements offered by higher-grade variants like the AC or BIN series.

Voltage Reference Part Context

This part belongs to the LT1460 Micropower Precision Series Reference Family. The family offers various accuracy grades and package options including SO-8, MSOP-8, PDIP-8, SOT-23, and TO-92. The GIZ suffix specifically identifies the industrial temperature grade version in the TO-92 package.
