LT1460FCMS8-2.5#PBF

Voltage Reference Overview

The LT1460FCMS8-2.5#PBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in an 8-lead MSOP package. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.15%. The device operates within a commercial temperature range of 0°C to 70°C and features a maximum temperature coefficient of 25ppm/°C. It draws a typical supply current of 125µA, with a maximum of 165µA, while supporting a minimum guaranteed output sourcing current of 20mA.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors for high accuracy and low drift
• Operates as a series reference architecture without requiring an output compensation capacitor
• Includes reverse battery protection to prevent damage from incorrect polarity connections

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific FCMS8 suffix against official documentation to confirm the MSOP-8 package type and 0.15% accuracy grade. Ensure the component meets RoHS compliance standards if required by your manufacturing process. Confirm that the commercial temperature range (0°C to 70°C) aligns with your system's environmental operating conditions before finalizing procurement.

Voltage Reference Selection Notes

Select this part when a stable 2.5V reference is needed in a compact surface-mount footprint. The FCMS8 variant offers a balance of moderate accuracy and low power consumption suitable for battery-operated devices. Consider the 25ppm/°C drift specification relative to your application's thermal stability requirements compared to higher-grade options like the AC or BI variants.

Voltage Reference Part Context

This component belongs to the LT1460 family of micropower bandgap references designed for applications demanding high precision and low power dissipation. The family includes various packages such as SO, PDIP, TO-92, and SOT-23, offering flexibility in board space constraints. The LT1460 series is engineered to replace older shunt references, providing significant advantages in power efficiency and settling time.
