LT1460DCS8-2.5#TRPBF

Voltage Reference Overview

The LT1460DCS8-2.5#TRPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in an 8-lead plastic SO package. It provides a fixed output voltage of 2.5V with a maximum initial accuracy of ±0.10%. The device operates within a commercial temperature range of 0°C to 70°C and features a maximum temperature coefficient of 20ppm/°C. It supports a minimum output current of 20mA, draws a maximum supply current of 130µA at the 2.5V option, and requires a minimum input-to-output differential voltage of 0.9V.

Voltage Reference Feature Summary

• Curvature compensation combined with trimmed precision thin-film resistors ensures high output accuracy and low drift.
• Capacitive load stability without requiring an external output compensation capacitor, facilitating fast settling times.
• Reverse battery protection prevents current conduction and protects the device from damage during reverse connections.

Voltage Reference Applications

• Precision regulators
• A/D and D/A converters
• Handheld instruments

Voltage Reference Procurement Notes

Verify the specific suffix 'DC' corresponds to the required 0.10% accuracy and 20ppm/°C temperature coefficient for the commercial grade. Confirm the 'S8' designation matches the 8-lead SOIC package requirement. Ensure the '#TRPBF' suffix indicates tape and reel packaging with lead-free finish compliance before finalizing procurement specifications.

Voltage Reference Selection Notes

Select this component when a micropower series reference with guaranteed performance up to 125°C temperature coefficient testing is needed. It is suitable for applications where board space is limited due to the absence of required output capacitors. Consider the 20mA sourcing capability for driving moderate loads directly.

Voltage Reference Part Context

This part belongs to the LT1460 Micropower Precision Series Reference Family. The family utilizes bandgap technology to combine high accuracy with low power dissipation. Variants are available in multiple packages including MSOP, PDIP, TO-92, and SOT-23, offering different accuracy grades and operating temperature ranges.
