LT1460BIS8-2.5#PBF

Voltage Reference Overview

The LT1460BIS8-2.5#PBF is a micropower precision series voltage reference manufactured by Analog Devices, housed in an 8-lead plastic SO package. It delivers a nominal output voltage of 2.5V with a maximum initial accuracy of ±0.1% and a maximum temperature coefficient of 10ppm/°C over the industrial operating range of -40°C to +85°C. The device operates from a supply voltage between 3.4V and 20V, drawing a typical supply current of 100µA (maximum 165µA). It supports a minimum output sourcing current of 20mA and features reverse battery protection.

Voltage Reference Feature Summary

• Curvature compensation combined with trimmed precision thin-film resistors ensures high output accuracy and low drift across temperature variations.
• Capacitive load stability eliminates the need for external output compensation capacitors, facilitating fast settling times and compact board layouts.
• Reverse battery connection protection prevents current conduction and safeguards the component from damage during incorrect polarity events.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'S8' denotes the 8-lead SOIC package. Confirm '#PBF' indicates lead-free finish compliance. Ensure the ordering code matches the required 2.5V output variant within the LT1460 family specifications.

Voltage Reference Selection Notes

Select this part when industrial temperature operation is required alongside high precision. The 10ppm/°C temperature coefficient and ±0.1% accuracy make it suitable for applications demanding stable references without the power overhead of shunt regulators. Verify input voltage headroom meets the minimum dropout requirement relative to the 2.5V output.

Voltage Reference Part Context
