LT1460BIS8-2.5#TRPBF

Voltage Reference Overview

The LT1460BIS8-2.5#TRPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., featuring an 8-lead plastic SO package and industrial temperature range (-40°C to +85°C). It provides a nominal output voltage of 2.5V with a maximum initial accuracy of ±0.1% and a maximum temperature coefficient of 10ppm/°C. The device operates with a supply current of 130µA (maximum) and supports a minimum output current of 20mA. It requires a minimum input-to-output differential voltage of 0.9V and functions within an input voltage range up to 20V.

Voltage Reference Feature Summary

• Curvature compensation combined with trimmed precision thin-film resistors ensures high output accuracy and low drift across the operating temperature range.
• Capacitive load stability eliminates the need for external output compensation capacitors, facilitating fast settling times and compact PCB layouts.
• Reverse battery protection prevents current conduction during reverse connections, safeguarding the component from damage.

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 ordering suffix #TRPBF confirms tape and reel packaging rather than tube. Confirm the 'I' grade designation matches the required -40°C to +85°C industrial temperature range. Ensure the 'S8' package code corresponds to the 8-lead SOIC footprint. Validate that the 'B' parametric grade aligns with the ±0.1% accuracy specification for your design constraints.

Voltage Reference Selection Notes

Select this part when low power consumption is critical alongside high precision, as it avoids the constant idle current draw of shunt references. The 20mA sourcing capability allows direct driving of moderate loads without additional amplification. Verify that the 0.9V dropout voltage fits within your available headroom relative to the input supply voltage under all operating conditions.

Voltage Reference Part Context

This component belongs to the LT1460 Micropower Precision Series Reference Family. It shares architectural similarities with other variants in the family, such as the LT1460ACS8-2.5#PBF, but differs in its specified temperature range and accuracy grade. The family utilizes bandgap technology to achieve stable voltage references suitable for various analog signal processing applications.
